IIRC, CRe doesn't give a lick about the Panose stuff, the (moderately crappy) heuristic only cares about the OS/2 name tables.
And, yeah, a common Family, and the Style properly set in the right place (but not in the family name itself) should be enough.
It's generally not an issue, but, gftools does the right thing, and as my notes explain, it also does part of the right thing to make both ACCESS & RMSDK happy too, so, win-win-win
