I have used parent parsers.

I think in your case merged_parser would become more of a child, like this:

>>> mom_parser = argparse.ArgumentParser(add_help=False)
>>> mom_parser.add_argument('--arg1', type=int)
>>> dad_parser = argparse.ArgumentParser(add_help=False)
>>> dad_parser.add_argument('--arg2', type=int)
>>> child_parser = argparse.ArgumentParser(parents=[mom_parser, dad_parser])
