Ok, it seems that there would be a precedence on 3012R + FR-7: A fellow called T_bone mentioned that
"I have not found an FR-7fz, but I am happily using an FR-7f on an SME long arm now. "
Would be interesting to learn what longer SME he used/uses and what the combo was able to offer.

So at least some people did try it...
