It's an almost impossible task. The series thrives on its tackiness.
Let's see:
If you make Edward a realistic hundred years old man, you end up with a character that a) would be so mature and beaten up by life and given that he's seen some raw shit in all his years alive, he wouldn't even look at normal girly Bella as even a viable candidate for him (read: boring-ass kid with a crush); b) He would 'cause he's a pedo--which he is in the normal franchise--but given that this Edward is a mature man, it would just be creepy as fuck and quite debasing for the chick.
Conclusion: Go with a). If you want to keep things positive it would inevitably lead to having to ditch the entire main love story and you are only left with the opportunity of turning the whole Twilight thing into a sort of coming of age story of a girl who finds a surrogate father figure in an emotionally numb sparkly vampire. She then proceeds to get caught up in a bunch of shit that sort of helps her define herself as she reaches her womanhood; while Edward, somehow, grows up into a less numb shell of a fucking twat, and develops to be well on his way to grow a pair of balls and man up as he slowly realizes that the world ain't just shit, thanks to his interactions with this doe eyed, naive, plain but ultimately well intentioned little girl.
The entire saga In short form: Bella falls stupidly and madly in love with Edward, tons of shit happes, she understands that the dude ain't for her, womans-up some, ditches wolf boy who can't keep a shirt on, finishes school and goes to college in Europe 'cause tuition in the U.S is fucking expensive as fuck and she has no monies, earns a rocket science degree, meets Edward again in her thirties and convinces the guy that still taking highschool courses makes him an underachiever and to use his immortality for something other than being self-obsessed whiny sod and he agrees to dedicate his wealth and time to science--Edward asks her out but she turns him down 'cause she's already with someone and so they part as friends.
Fast forward two hundred years into the future and humanity is finally taking its first baby steps towards space expansion in the sea of stars, thanks to our resident sparkly vampire having spent all his time doing the science thing (i.e. something useful). Now, captain Eduardo (Edward?! Swoon!) captains a ship named...Dun! Dun! Dun! BELLA! into an expedition full of adventure and excitement!
There. I just fixed fucking Twilight while still keeping it a girl power trip.
