GFNI only does 8-bits and sticks you with a single modulus. But for some reason I'd forgotten it completely, you're totally right to give me a mystified response.
(FWIW, it's possible to project elements from one field to another isomorphic field, though it takes enough operations that for fast code like RS decoding the conversion is probably performance limiting).
For hybrid codes GFNI should be sufficient, though for things like using RS at 16/32 bit sizes it's not.
