Misc MRX mag question

Hypothetically if a person were to modify a pump action rifle receiver that uses an AR magwell to fit MRX mags would that be legal? If so would modifying the magazine to have only one set of fins and modifying the rifles’ magwell to fit the one set of fins be legal?

You can change a mag well but not a mag
