QUOTE(Livi Lovegood)
the likely hood is that lily and james will see ginny as harry's ideal woman because that is exactly what jkr made her to be.
I'm very well aware of the interview. I think lots of PK-ers here are.
QUOTE(www.dictionary.com)
Ideal:
1. a conception of something in its perfection.
2. a standard of perfection or excellence.
3. a person or thing conceived as embodying such a conception or conforming to such a standard, and taken as a model for imitation: Thomas Jefferson was his ideal.
4. an ultimate object or aim of endeavor, esp. one of high or noble character: He refuses to compromise any of his ideals.
5. something that exists only in the imagination: To achieve the ideal is almost hopeless.
6. Mathematics. a subring of a ring, any element of which when multiplied by any element of the ring results in an element of the subring.
Bolding mine.
"Ideal" does not mean perfect, as is supported by the dictionary definition(s). It's an idea of perfection-- it doesn't mean it's perfect. So, Ginny is not perfect for Harry.
Ginny? Ideal? An idea of perfection? Ginny represents what Harry thinks is ideal. Ginny represents what he thinks is perfect.
QUOTE(J.K. Rowling @ MN/TLC Interview)
I think she's funny, and I think that she's very warm and compassionate. These are all things that Harry requires in his ideal woman.
Compare/Contrast:Ginny: friends with LunaQUOTE(Chapter 15: The Unbreakable Vow @ Page 311, HBP)
"Oh it's been all right," said Luna. "A bit lonely without the D.A. Ginny's been nice, though. She stopped two boys in our Transfiguration class calling me, 'Loony' the other day--"

gives Harry singing cardsQUOTE(Chapter 13: The Very Secret Diary @ Page 258, CoS)
"Right," he said, sitting on Harry's ankles, "here is your singing Valentine:
"His eyes are as greena as a fresh pickled toad,
His hair is as dark as a blackboard,
I wish he was mine, he's really divine,
The hero who conquered the Dark Lord."

defends HarryQUOTE(Chapter 24: Sectumsempra @ Page 530-531, HBP)
[snip]"Give it a rest, Hermione!" said Ginny, and Harry was so amazed, so grateful, he looked up. "By the sound of it, Malofy was trying to use an Unforgivable Curse, you should be glad Harry had something good up his sleeve!"
"Well, of course, I"m glad Harry wasn't cursed!" said Hermione, clearly stung...[snip]... And I'd have thought, seeing what this has done to your chances in the match--"
"Oh, don't start acting as though you understand Quidditch," snapped Ginny, "you'll only embarrass yourself."
[snip]...Harry, however, little though he knew he deserved it, felt unbelievably cheerful all of a sudden, even though none of them spoke again for the rest of the evening.
QUOTE(Chapter Four: Flourish and Blotts @ Page 70, CoS)
"Famous Harry Potter," said Malfoy. "Can't even go into a bookshop without making the front page."
"Leave him alone, he didn't want all that!" said Ginny.

chocolate sceneQUOTE(Chapter 29: Careers Advice @ Page 577, OotP)
"It's Easter Eggs from Mum," said Ginny, "There's one for you...there you go." [snip] "Are you OK, Harry?" Ginny said quietly.
"Yeah, I'm fine," [snip] "You seem really down lately," Ginny persisted. "You know, I'm sure if you just talked to Cho..."
"It's not Cho I want to talk to," said Harry brusquely.
"Who is it, then?" asked Ginny, watching him closely.
"I..."
[snip] "I wish I could talk to Sirius," he muttered. "But I know I can't." [snip]
"Well," said Ginny slowly, helping herself to a bit of egg, too, "if you really want to talk to Sirius, I expect we could think of a way to do it."
Hermione:says Voldemort and IT CALMS HIM DOWN, in contrast to Ginny saying it and him NOT NOTICING IT AT ALLQUOTE(Chapter 15: The Hogwarts High Inquisitor @ Page 293, OotP)
He looked helplessly at Hermione, whose face was stricken.
"Harry," she said timidly, "don't you see? This... this is exactly why we need you... we need to know what it's r-really like... facing him... facing Voldemort."
It was the first time she had ever said Voldemort's name and it was this, more than anything else, that calmed Harry. Still breathing hard, he sank back into his chair, becoming aware as he did so that his hand was throbbing horribly again.

gets Harry out of his room... the ONLY one who could get Harry out of his roomQUOTE(Chapter 23: Christmas on the Closed Ward @ Page 440, OotP)
"I know you're in there," said Hermione's voice. "Will you please come out? I want to talk to you."
"What are you doing here?" Harry asked her, pulling open the door as Buckbeak resumed his scratching at the straw-strewn floor for any fragments of rat he may have dropped. "I thought you were skiing with your mum and dad?"

Hermione is pretty much the only one who believes him when he says he "didn't put his name in the goblet".QUOTE(Chapter 18: The Weighing of the Wands @ Page 317, GoF)
"Hello," she said, holding up a stack which she was carrying in a napkin. "I brought you this... want to go for a walk?"
"Good idea," said Harry, gratefully. [snip]... Harry told Hermione exactly what had happened after hehad left the Gryffindor table the night before. To his immense relief, Hermoine accepted his story without question.
"Well, of course, I knew you hadn't entered yourself," she said, when he'd finished telling her about the scene in the chamber off the Hall. "The look on your face when Dumbledore read out your name! [snip]..."

when Hermione reassures Harry that he's NOT a bad kisserQUOTE(Chapter 21: The Eye of the Snake @ Page 405, OotP)
"Oh," said Ron, his smile fading slightly, "Are you that bad at kissing?
"Dunno," said Harry, who hadn't considered this, and immediately felt rather worried, "Maybe I am."
"Of course you're not," said Hermione absently, still scribbling away at her letter."
NOTE: I couldn't have gotten this done without Arthur (
Hermione's Hero) and James (
The Obsidian Warlock)'s help. Seriously, this wouldn't have been completed.

ANOTHER NOTE: The page numbers might differ. I have SS/PS, CoS, GoF, and OotP in British edition, and PoA and HBP in American edition.
