RISC is a 32 or 64 bit arch. There was some discussion of a 16 bit version but it didn't get traction. 8 bits wouldn't really work: who wants an 8 bit cpu with 32 bit wide instructions? From a software perspective I could see some attraction to new 8-bit architectures, but in market terms it is legacy space by now, it seems to me.
