Well, I've gotta confess my patience finally gave out on waiting to hear what was going to happen with the BMR. All indications seem to be, at this point, that Dennis is not going to be producing them again and no telling what Salk will wind up doing with the design. That said, I wound up reaching out to Rick Craig, and after going back and forth via PM, I decided a true WMTW center design that would match the BMRs would be better than even a BMR on it's side, so Rick is doing a kit for me and I'm going the (semi) DIY route. The kit is based on his Ceramica Center design with some modifications to better match the BMR. One of my daughters is actually pretty accomplished at building things and the relatively simple box for the center (we're going with a sealed design) should be a piece of cake for her. The challenge, of course, will be in finishing the cabinet which is something I will handle and have given a little thought to already. Rick's kits are pretty complete, down to an assembled crossover and cabinet design, so I'm not anticipating problems with the actual "install" of the drivers, etc.
Hopefully I'll be able to document as much of my (and my daughter's) side of the project as possible and, certainly, will provide my listening impressions.
