@kaia No.
A few years ago, Google introduced the new "Play Integrity API".
Google Wallet requires at least the "MEETS_DEVICE_INTEGRITY" verdict (which requires a signed ROM loaded in by a locked bootloader).
At the moment, custom ROMs can only get the "MEETS_BASIC_INTEGRITY" verdict (due to needing an unlocked bootloader to be able to load unsigned/unapproved ROMs).
