I realize that the 612 is wider than the Veriwide 100, but otherwise why not? I also note that with lens it is far out of range for people like me, but then so is a Veriwide in good order.
Have you looked into the ProPaq line of modified Graflex XLs as sold by SKGrimes? Again, not quite Veriwides but in the spirit. I've suggested to Adam that he should be able to beat Alpa handily on price but he hasn't taken the hint.
And, come to think of it, I see that Capaul & Weber are now offering a modified Linhof Super-Rollex back that gives 56 x 84. They want silly money for it, also for the camera bodies that accept it, but an Alpa 12 with slightly long nominal 6x9 back and a short lens is in the spirit too.
About the suggestion above that a Graflex SLR be revived, Ron Wisner tried. IIRC, his well-made wooden box got good reviews but sold very poorly.
A subtext of this thread is that the new alternative to clapped-out old cameras should be relatively inexpensive. But many of the clapped-out cameras nominated for modern replacements were pretty expensive when new.
