Tons of cars fet drivetrain swaps! It’s not bad, lots of kits out there and a little custom fab goes a long way. I have personally put hemis and 8hps in JKs, swapped an 02 drivetrain into my 87 YJ, have swapped a gas V8 rover to a diesel td5, have many auto to manual and vice versa conversion. Hell my co worker just put a Corvette engine in a rover backed by a 6 speed tremec and an adapter plate to the original rover t case. It’s surprisingly simple! Hell u can even convert ice to elec pretty easily if u have the where-with-all!
