Ben,
Reading Paul's question - carefully - it would appear to me that (a) he can no longer use this scanner, (b) he has no intention of buying another scanner, and (c) the scans he has already made with it are in sRGB working space, which means that any data that existed pre-scan exceeding sRGB is now clipped and gone forever. In those conditions, if he needs more gamut he needs to reprocess probably along the lines he is thinking.

So long as the scanning software isn’t doing any sort of automatic adjustment or clipping, especially per-image adjustment, the color space that it tags the resulting images with shouldn’t matter. You can simply profile the output of the entire capture process, ignoring any embedded profiles.

Only you can decide if the effort is worth what you’ll put into it. You might or might not gain anything from the different workflow. The A7R with good glass should easily out-resolve 645 film; unless you’re looking to reproduce the shape of the individual film grains, it should be all you need as far as resolution goes. And it definitely has more dynamic range than any film. Sony has had some trouble figuring out RAW file formats, but the compression artifacts they’ve introduced shouldn’t be a factor for what you’re describing.
Were I starting from scratch with digitizing medium format film, I’d go with a DSLR workflow. But if I already had a quality film scanner, I’d be reluctant to stop using it.
Cheers,
