This is funny, i had a similar idea but for a sidekick. I havent seen any sami ifs rigs myself, but there isn't any reason you couldn't make it work. So the idea is good, after all guys with 5000 pound, 350+hp rigs can run around on 35+ inch tires, a little zuk could get away with more simply being lighter. Plus, i have a long travel fetish and most LT kits for any rig out there is costly, so i wanted to drop ifs from a newer fullsize tundra on a kick. I figured tundra would be better than 2500 gm ifs for a few reason: coilovers instead of torsion bars (i think any t-bar will be indexted too stiff), 6 lug pattern (aren't they?) Instead of 8, making matching wheels with an fj80 or yota real axle convenient. Also, totalchaos makes nice UCAs that boost the travel a couple of inches. A fullsize ifs will have more travel, be tougher and have stronger brakes and a wider track width.
Only problems i see are: the additional weight and the track width being too wide. Its not like proper ground up deigned LT stuff where the U&LCAs are mounted close to the center of the frame as possible. With a different diff you could probably narrow it down along with some modified CVs but that's beyond me.
