Not that I am aware of. Not many people use bluetooth tethering, considering wifi to superior in many regards. Your best bet is to read the initial post descriptions of each custom ROM i.e. the custom ROM support threads to see if that is a feature in any custom ROMs.
It would be far easier to just find a bluetooth tethering app and install it though.
