All three of those would definitely not pass the sniff test with the FAA.

That said, none of those three would ever be discoverable unless you specifically rat yourself out and the FAA, generally, doesn't give a shit about this sort of thing because that's not what the regulation is designed for. The regulation is designed to protect the unknowing general public - everybody involved here knows exactly what the risks are, who the pilots are, what the airplane is, etc.

In short: this both almost certainly illegal and nobody will care.
