I've got the last round of a 5 round series of the fwd r's tonight... I don't think any rwd will ever be comparable for racing. maybe for 1 lap, but the main 'thing' with these cars is the way they utterly destroy front tyres if given half a chance. I still hate fwd, but actually *racing* these cars, working on race setups, managing overtaking lines without destroying tyres, is really very enjoyable. I don't think a rwd competitor in this class would suit. I guess if you made the rwd a little slower it could be interesting over the length of a race... but I still think it would take the charm from racing these things.
