I'm not objecting to subclassing, per se.

Hmm, this is a problem. I'm really not sure subclassing makes that much
sense here. At the very least, you probably need to provide your own
new() method.
I'm really not sure how far (if at all) we should go in trying to make
DateTime.pm suitable as a superclass for other calendars. Look at the
mess that is the Java datetime stuff, and note that they tried to do this
;)
