I've did some looking and asking around.
Based on my findings I'd say if I were going to build a Super Franken, non-holed 16610 using a gen mvt and dial I'd opt for a Sean case with gen bezel assembly.
While a gen dial will fit the TC case, it seems the dial opening in the sean case is exact for the gen dial. (that makes for an easier install and a more secure dial)
It's safe to say that if you're going with a gen mvt. you'd go all gen everything with the exception of the mid case.
Expensive build (no doubt) but it would certainly be a one of a kind and it sounds like a very fun and gratifying project.
To me a build like that with everything gen but the case would essentially BE a gen.
But that's just what I would do.....IF I could afford to....which I can't.
A build like that would mean more to me than any gen I could buy.
It's all about the journey, my Brother......not the destination (though the destination "would" be very rewarding.
Please do keep us posted on your choice and progress.
