While I don't think such a thing exists, I expect that such an adapter could also be made in the form of a teleconverter, like the Canon FD to EF lens adapters.

The Canon one was a 1.25× teleconverter to adapt a lens with a 42mm register to EF mount with a 44mm register.  That's 2mm difference.  The difference for RF to EF mount is 24mm...

I can't be bothered to do the sums but I'm pretty sure the minimum magnification would be high enough to make the effective f/ number unusable.
