They made an AWD transfercase in the Dakotas aswell. Someone else will have to help you with it as I don't know much about going from a 2wd truck to AWD. But I promise you it would be a HELL of a lot easier then what either of your friends have planned. I've never heard of anyone making either of those cars AWD, the crv parts are true but they sure as hell won't hold at 500hp.
I would just stick with the 2wd and get some bigger tires out back, unless you REALLY want AWD.
