To my knowledge, the capabilities are part of the descriptor which must be
available before the AE is initialized. You cannot retroactively change the
descriptor of a method from within its initialize() method.
It would be nice to have something like this, though. But that would also mean
switching any flow controllers which use this information from a static planning
to a dynamic planning approach.
How about filing a feature request against the UIMA framework?
