I've done my own take on the races for RMU. I ended up giving them more development points just to they had the flavor of the RMFRP versions. I told my players that they should pick the Shadow World races as they are inherently more powerful than the base RMU ones...
I've converted the following: Duranaki, Myri, Sulini, Yinka, Y'nari, Laan, Erlini, Shuluri, Laori, Haid, Numari, and Jameri.
