I agree on the Al tcases. Unless of course it is an atlas. 
A front D60 hub with Warn hubs sticks out. A lot. with 39.5" Irok's and ~5ish" of backspacing I whack mine on rocks. Even doing simple wheeling.
Hi, I honestly believe that a mini on 44's is not really a good truck to compare a 40 to. Most 40;s use springs that are very flat. For a mini to fir 44's you are talking about moving the axle forward a bunch, and gining it a TON of lift. Or removing part of the hood for the tires to not rub
BTW, I assume that the rims were stazworks. Who makes a 44x14.50 tire?
Again, I think buy as new as possible and sell the tranny/tcase and get something simpler
from what I understand most gm trucks use a PS box that is identical to the standars Saginaw but mounts on the outside of the frame. I have looked at one for comparison but think that it would not be the cleanest install. All of the AC system will work except for the in cab portions.
You can make just about ANY motor fit in a 40 with a bit of massaging. It all depends on how wild you want to go..
Rear driveline would probably work but would be HUGE. typically trucks use a bigger diameter DL than 40's do. Which is good for strength but bad for rocks. Front driveline is a tossup. I have the impression that the front DL would get in the way of the tranny.
Additionaly the front 60 typically has a 1310 U joint flange. I would upgrade that while you are at it.
