Yup! Trivially different from what we did w/ SSers in 09.

The biggest pain was how to cleanly attach to the face of the ballshifter w/ the extra standoff we had.

It's clear in CAD, but not in the pic. The lower hex standoff doesn't attach to the ballshifter, but rather to that .25" thick plate with a hidden flathead 1/4-20. The plate then attaches to all 3 ballshifter mount holes and is a large bearing surface on the face. This should really adequately handle the moment reaction.

Since we don't have one on hand, we were unsure of the strength of that face. We assumed that since IFI put in hex bores for standoffs, that small local face contact for moment reaction would cause damage. So right now we're assuming we need that large plate to touch so much.
