You would first need an actual working RISC-V silicon that it would be worth porting to. Not the essentially demo chips with poor performance that are around now. RISV-V is a lot of talk and hype but the actual silicon that you could buy and implement into a product is hard to come by. With the exception of a few small microcontroller efforts (GigaDevice, Sipeed).
