Default MOA Conversion?

I am still knee-deep in my current TRX4 project, and have started to eye my next one. This one that I am looking at will only have one drive axle with no room for any sort of a transmission. The obvious solution is a MOA axle, but I would REALLY like to use a Traxxas portal. I have done a little searching, but really couldn't find anything, so does anyone know if anyone has converted a TRX4 back axle to MOA?

Domo arigato!!!

Haven't seen it done yet. I'd imagine that it could be done in a similar fashion to how people used to convert the Losi Comp/Night Crawler to MOA, by mounting a 5mm pinion where your driveshaft used to be, then making a motor mount (gonna have to get creative, maybe use some aluminum angle and attach to existing holes on the trx4 axle?) that places the motor basically in line with where the driveshaft was, just higher. Problem there is that it makes the axle very long, and places the motor up pretty high. What's the application you're looking to use this in?

Rear portal boxes from High Altitude Performance (Almighty Malich here on rcc) and slap the boxes on an xr-10 moa axle.

There are lots of other options but that's about the easiest possible.
