So, thinking the 6.0 would be an easy swap.

Is his Sub a 3/4ton? if it is, the difference in the 4L80E on the 3/4ton and your 4L60E is going to give you a seat of your pants difference in driving experience. And chances are he has a towing gear ratio. Again, speculation.
I get where you are coming from though.
