Following is a brief summary of the motor mount we decided to try for Phase I:

We picked it up on eBay for $25. It seems for material selection, measuring and machine time, it was worth the cost for a quick and inexpensive place to start. As noted above, our thoughts for a dual Velineon system and the Traxxas E-Maxx motor mount were discarded for a sinlge motor / ESC design.

First trouble we had was the lower bracket portion was above the chassis so we had to make a spacer to mate up properly. Second, the central diff drive hole was not positioned properly to match up to the diff mount screws. We were able to get around these with some "adjustments"

We also made our own "shelf / bracket" for electronics mounting, so we did not use the top plate that came with the package.

I like the idea of using angle stock, as I think the lower bracket anchored to the chassis will provide stiffness given the weight of the cantilevered motor would normally only be supported by either just bolts thru the bottom, or anchoring to the diff assembly.

We will also be "skeletonizing" it for weight reduction and increased surface area for inhanced passive cooling for the motor.

Below is a picture of the base part, more from our buggy in the coming days and weeks as we put it together and begin testing under power:
