"It makes me think of putting one in my Super ES when I get to that stage
since if I ever ground loop and have to get out while inverted, that's the
best way."

First, how would you ground loop an ES?  Second, you'd be pretty hard
pressed to flip it over with that wing span unless it went over on it's
nose.  Finally, there's already an opening on the side of the ES if you can
make a way to open your baggage door from the inside.
