The 55cm demo (congrats on getting it, Michael!) has the no-kink geometry, compared to the 50cm demo (kinky). I used to think the kink detracted from the look... but my mind's now used to the look, and the 55cm no-kink looks to be the outlier!
I also think large frames w/o TT or diagatubes look strange now. Maybe if I look at MCRB long enough, they'll look fine, too? For fabricating a "true mixte", the limitation is the lug-- Riv would have to use a different headlug and seat lug ($$$$) or perhaps do a filet braze to the headtube? I think Liesl mentioned that her custom Appaloosa will have a diagatube of this sort. (As the frame is too small to have a Riv-normal diagatube.)
