I'll be putting out an RSF editor relatively soon, depending on when I get a little bit of time to work out the last pending issue with the code before I start putting in GUI. My suggestion is to make up a whole bunch of faces (or whatever, however many you want), test them out by merely replacing current ones (just to test) then package them up and wait until either 1) I'm ready to put out a new HugeMod, 2) I release the editor.
