3 speed to 4 speed auto swap?

I was wondering if anyone has swapped a 3 speed auto out for a 4 speed auto in an early car. I am not sure how feasible it is at this point but just throwing it out there. Any thoughts?

possible--

benefits include higher stall speed converter, stronger trans, one more gear.

make sure you get all of the pcs to do this (from donor car).

I believe there was no difference in torque tubes between the two autos.

maybe someone else can confirm this?
