But...
If you slow the drill down to the 5500 RPM free speed that the Chiaphua has and then ADD the Chiaphua to the input to the drill gearbox, you will be inputting something like 4 N-m to a gearbox designed for .65!
Let me know before you turn on the power as I would like to have me safety glasses on...

Well... that said... would it be better to gear up the Chiaphua to 20,000 RPM and stick both it and the drill motor into the transmission (100% over torque?), or would it be better to gear both motors past 20,000 rpm, and stay in-spec for torque? How fast can you make that poor little transmission's input spin, anyways?
