L-18 Birddog aerobatics?

So, writing a story where a bunch of young college-age
women discover some crated L-19s in a corner of a hangar.
I'm planning that they assemble them under the watchful
eye of a semi-retired pilot and A&P who can sign off on
the FAA paperwork.

Once the airplanes are assembled and flying, then what?
I had the thought that the women could dress up as WW II
Wasps and go to air shows. It would be funny as hell to
have them put on a low-horsepower version of a Thunderbird
airshow.

What kind of vaguely aerobatic-like things could a stock
L-19 perform? More than once?
