I have to rest my Milwaukee drill and use it at about 1/3 to 1/2 duty
cycle because it gets hot.  I haven't burned it out, but it loses a
lot of power when hot.  This is find because it keeps the winch from
overheating too.

I am a lot more worried about the winch failing than the drill failing.
A failed drill does not put the tower at risk.  And in a motorized 
winch, the motor does not put the tower at risk in any event.  What
I am worried about in a motorized winch is any sort of "brake" that
may fail.  I think you still want a worm drive in a motorized winch
as a safety mechanism.
