There's n-bit RISC-V implementations. The registers are still 32 or 64 bit wide, but the ALU is smaller and takes multiple steps.

One such implementation is open source, but I sadly don't remember the name and can't find immediately.

There are oh-so-many, but the one you think of might be Olof's SERV (https://github.com/olofk/serv)

Yeah but the registers do not get smaller in that implementation.
