If I'm not wrong, although it would be a different OS, it would still be based on Android, just that the OS isn't stock Android anymore. There shouldn't be any problems with this as you'll still be using the Android APK/Google Play Store for installation, i.e. it's the same version.

The only potential problem that I can foresee from trying to issue and use a transfer code on the save device is that the account wasn't even deleted in the first place, which makes the entire issue moot. Aside from that, if the device was reset and all data was lost, it should be treated as a brand new device, hence I don't believe there would be any problems.

Sorry for not being able to give any concrete answers, as I don't think we've had a similar case before. But I am relatively confident no issues will arise so long as you take the necessary steps to safeguard your account with the transfer passcode.
