If you can put historic tags on, or use an OBDI car, you bypass that problem.
I actually don't think that the physical manual conversion is going to be *that* difficult. It's just that you need access to a machinist who can make you a custom bellhousing. That's probably a better route than trying to source an extremely rare and probably expensive transmission. R129s were sold with three pedals from the factory, so you can source the pedal box and hydraulics. (It's worth noting that in the linked thread, people point out that it's actually highly unlikely that it was a 928 transmission used and speculate that it was probably a BMW unit.)
Hell, it's likely that the V8 and the V12 share bellhousings, so there might even be an off the shelf adapter out there.

Thanks for the input.
Not worried about designing custom parts or having them machined. That's what I do for a living and I know dozens of places that can make it. It may get expensive, but that's another issue along with getting it all to fit in the space there is.
Is the OBDI/II thing needed for the car to work, or is it an emissions-related thing in order to get plates? I assume the latter.
