42RH / A-500 in a Duster with pictures.

Is it possible to convert the A500 to non-lockup? I have a spare good non LU 904 lying around in the garage. Just convert the input shaft, pump and get a non-LU valve body and the use a non-LU Torque converter and be good to go?
I think it is possible after looking at exploded diagrams of the A500.
I did a non-LU conversion of the A999 which wasn't too bad.
