Since aluminum is non magnetic, I would assume a mag-mount vertical would
not couple properly to a aluminum ground plane.

Thoughts ?

CL -- I doubt, therefore I might be !

I tried this on a 2M antenna and it didnt work so well. My theory was that
since the antenna was not firmly attached to the Al then the capacitve
coupling between the base of the antenna and the Al groundplane was off.
Fixed the problem by soldering radials to a coffee can lid and placing the
antenna on this.
