Basically, with enough time, money and adapters, anything can be adapted to fit anything else. You may have to change input shafts, and I would recommend keeping the 2008 transfer case, that way you won't have to worry about adapting that. I' pretty sure you'd need the driveshaft, too. I think it can be done, without too much work. You'll have to decide whether it's worth it.
Come back and let us know how this plays out - I might be interested in putting one in my 1990 if it's not that complicated.
