Afraid not. These things usually require hardware attestation to ensure you're running the exact software Google wants you to run. Now, if someone figured out a way to bypass it, that would probably work for a bit. But it's a cat and mouse game.
It's not just what Google wants you to run, it's what Google promises to some of its customers through a face it has on one of numerous facets(facing banks in this case) as what they let users do with phones, and a humanware chain of trust that allows the server and the phone to be viewed as sort-of secure computing environment.
From an idealist standpoint, it shouldn't be done that way by taking away rights from users, but trivializing it as how specifically Google wants you to do it isn't accurate either.
