Sounds like a fun problem to have.  There are some open source NMS products out there that integrate with RANCID and can probably write out the file for you, otherwise you would need to modify how RANCID works and have it switch to the type of device after login with a show ver command or something similar.  Let us know if you come up with anything though, I like the idea of having the device login decide the type, or at least a discovery mechanism for RANCID that would write out the proper lines to .cloginrc.
