What end goal are you trying to accomplish?
IS this a show vehicle? Do you really want to beat up on it off road or lifting for looks?
If you really want to wheel a 2wd, I suggest a spring lift like Rustys or the Frankenlift and a rear locker.
If you are going for the wow factor and just want to draw atention to it for show/sponsorship purposes, then a larger lift would be better. You could use the 7up and I would imagine there are things you wouldn't have to deal w/ seeing you only have a 2wd. I wouldnt try wheeling it much though as trying to turn larger than 32's on a 2wd off road is going to suck. On the street it should be fine (?).
It sounds like you have a pretty unique vehicle now. Maybe upping the overall performance of the vehicle would be a way to go? Custom paint?
Custom body work? Anyhow, knowing what You really want to accomplish will help us to spend your money.
BTW, I voted keep it slammed. ORiginality rules. A mostly non-functional sky high 2wd to me is lame. If built up sweet to actually fly fast off road as a lifted 2wd, now you are talking. A pre-runner style KJ would be Killer and Unique too. Just my HO FWIW.
