I'd suggest starting a new thread on python-list (or stack overflow or
whatever) explaining what the heck you're trying to do here and asking
for higher-level advice/suggestions, because your current
implementation strategy seems to have placed you on a path that is
rapidly descending past "spaghetti" towards "tentacular".

(Or alternatively I guess you could go all in: Iä! Iä! Metaclasses Fhtagn!)
