This may be stupid but can the three deathly hallows some how represent Harry, Ron and Hermione..

It was Hermione who wanted the cloak.

Wand: Ron has always been overshadowed by his brothes. He wanted to do be the same like them and have the family impressed with him too. The wand represents power, so maybe Ron wanted power in able to do that, or in general, power so his family will not look down on him.

Cloak: Hermione has been the shy, but smart one. She's always done things that people might find weird at first, but make sense later. She is confusing at times [mainly because people don't understand her.] The invisibility makes people hide from everyones' eyes, but it makes a giant difference and people don't know what to expect next. It could represent Hermione.

Resurrection[sp?] Stone: Harry has always missed his parents and in DH he did say he'd rather be sleeping under the snow with them. He's also lost so many people that he mourns. The Resurrection Stone brings your loved ones near [which is what Harry wants], but it also has something to do with death [which Harry faces and he also would rather die then see everyone else dead.] At the same time, the stone does not bring someone truly back and Harry, in all his years, understood that all the people dead would not come back. It could represent Harry. :)

Interesting question :D

edit: SiriusSeverus, yes, I understood the question, but the hallow they picked might show who they are more rather then the hallows in general.

Just a suggestion... Can we try actually reading the question first? At no point does the question...er say that Ron said he wanted the cloak, just that the cloak could represent Ron. Same goes for Hermione and the wand. The questioner simply asks if you think it possible for the Hallows to represent the Trio, then states her (?) reasons for why She' thinks which represents which.

A good question.
I like the idea of wand/Hermione for the power She' has as a "mudblood" being the smartest witch of her age, but understanding that being simply "clever" isn't everything. (Ref: "books and cleverness? There are more important things such as friendship and bravery")

Cloak/Ron, for always being overshadowed or "hidden" by his more popular sister, his funnier brothers, his smarter brothers, and of course, his famous best friend.

Stone/Harry, because he lost so many people close to him, and would understandably want to see them again. However, he also managed to see past his own longing, and understand that there are much worse things than dying.

When I first saw this question, I was like... No. They don't.
Now I've thought about it, I definitely see where you're coming from. As for wether it was intentional, or a happy (if somewhat arguable) coincidence.

Wow, that was an awesome question! I think it's definetely possible, since JKR hardly ever writes anything without a reason.

I think it's

Hermione= the cloack. When you look at the story of Beetle the Bard, you notice that the cloack is the only object out of the three that has the power to "outsmart Death". Hermione thrieves to be cleverer than anybody else, so this would be very fitting to her nature.

Ron= the wand. This was a very easy one, since already in the first book we are introduced to Ron's desire to be respected and admired (when he looks into the mirror of Erised). The wand represents power and uniqueness, which would appeal to Ron who's always felt that he's a little cast aside by his brothers and later his smarter/more famous friends.

Harry=the stone. Also this was quite an easy one, as everyone's already pointed out. Harry loses many loved ones throughout the books and would hope to get them back - remember how he was certain that he would be able to communicate with Sirius after his death by using the mirror? And how he hoped in the Prisoner of Azkaban that his father would still be alive to save him and Sirius from the Dementors? The stone would be very tempting to him.

I believe the Deathly Hallows represent the self-centered wishes and desires Harry, Hermione and Ron have and which they must give up in order to save the world. I think that the symbol of the Deathly hallows is also important, since it portrays all of the Hallows together. Harry, Hermione and Ron needed to work together in order to succeed.

Ron? ... Shy?

But you do have a point...

I remember in Deathly Hallows Hermione says, "It's obvious which one you'd want, though?" or something and Harry says the stone, Ron says the wand and Hermione says the cloak.

no they don't really fit their characters. Sure Harry could use the stone to bring back his parents, and Hermione deserves the wand because she knows the most spells,but the invisibility cloak doesn't go with Ron. If anything he wanted to be seen & heard more (because of his brothers overshadowing him), he didn't want to become invisible to the world.
