The best solution to me seems to remove the fan from the light switch
and give it, it's own separate pull cord switch with a neon indicator so
that you can tell if the fan is actually on or in time out.

Any reasons why I can't do this or is it just a bad idea?

How about?:

It will control the fan based on humidity, and you can always override
it with a quick (silent) twist of the knob. You ought to have an
isolator somewhere else for the fan as well, but since this is not for
day to day use, it can be a clunky ceiling switch type.
