Currently this is not supported, but it would be a nice feature.

You can probably already do this. I'm not 100% sure what you want to
do, but it's certainly possible to define an argparse.Action that
loads a module when it's invoked. It might look something like::
class MyAction(argparse.Action):
def __call__(self, parser, namespace, value, option_string=None):
mod = __import__(value) # or whatever
