All been done before.
There is a very thin line with air show flying. The aim is to demonstrate what skills you possess. Not, as in this case, skills you dont possess.
If this is not a case for pulling a licence, I don't know what is, considering the 3rd party risks. Go fool around out in the desert for example, to ensure when you screwup, you dont kill others.
It should be left to the experts to demonstrate aircraft and skills.i don't claim to be one.
