"Cons" too strong of a header, couldn't think of anything better though. ;) Thanks for your responses. This is one of the great things about the boutique watch industry and their direct interaction with their customers. A few additional points as follow up...
1) Looking back I see the challenge with the handsets vs. the rehaut, presumably the length of the former doesn't jive with the extension of the latter. Becomes a question of which ticks the button more, the rehaut (which is beautiful) or the preferred handset. First world problems.
2) Second point definitely not clear - looks like I was on the sauce at the time. The original (signature it seems) markers seem a bit bulky for my tastes, but this is what customization is for with the ability to select the batons as an alternative (but not the rehaut). I think the simpler batons allow more attention to be focused on that fantastic case.
3) I appreciate the challenge of a small operation balancing costs and economies of scale. So far as the date window is concerned kudos that you have correctly chosen dark or light date dials accordingly.
4) I have no objections to the HEV, as I stated I think they're cool despite being superfluous. Given there are no relevant cost considerations I'm all for having it in there.
5) Consistent brushing (top to bottom) on the face will work much better with the bracelet. Although, damn, that radial looks cool that conflict notwithstanding.
6) As for the rubber strap option, another consideration instead of a full-on custom fitted model could be one that clips into the bracelet endlinks. Kind of like with the Tudor Pelagos. You get the integration without the fuss of a fully molded rubber. Don't know if it's six of one, half dozen of the other for production and manufacturing.
7) Not committed yet to a purchase, but as a buyer/collector I would definitely be swayed by the fitted rubber strap and/or skeletonized custom rotor as a pre-order incentive. Each would definitely set this watch apart.
