You know, I'm in favor of mods that actually do something useful. I can't see stretching the swingarm on this. Really, from the sounds of your plan, it's not like you're going to get such radical accel' out of it that it needs the lengthened swingarm, and, with the stretched swingarm, it won't turn.
That is, unless you're just going for the drag-racer look. Then, by all means, prep it to go in a straight line. If you intend to ride it on the street, don't bother.

Hey Bro, I was J/K ya.
I like bikes that are "different" Giving it the drag bike look would be cool, just think about what the other guy's said about stretching it to far will really affect your cornering.
Good luck with your project, when you get it done post some pics.
