Burro Crane + TMCC = TMCC Operating Crane Car.
As John has pointed out, the killer in this project is the ac motor. That motor requires the AC Commander which has a much bigger footprint over the mini commander. If the burro crane had a can motor, then you might be able to fit the mini command in for basic functions of running down the track. To add full functionality, I don't see it as a viable project since there is so much to change. In the end, you end up with a TMCC Operating Crane Car.
