I have a hard time thinking someone would have fun being the referee only, so it would have to also play a PC at the same time.
In that case, my preference is to keep number secrets to the players (and that means also when I am a player myself) so I wouldn't like much that the players set the DC since they would automatically know how high they should roll. But I suppose other gaming groups can be fine with this.
Number-setting aside, letting the players participate in deciding which rules to use is not bad at all. But again, I wouldn't want to be the rules referee, if that's the only thing I'm going to do at the table, and I don't know anyone who would, so I'd rather think it would be easier if "referee" is just a collective role for everybody.
