Maybe that would work, but I'm also concerned about messing something up. In particular, tripping some bot detection/account duplication algorithm and getting my account banned and all its content gone. I'll suffer the small annoyance rather than risking the black swan disaster.

I wouldn't worry about that. I've had multiple Amazon accounts (with different emails!) going back many years. Never been an issue. They even make it easy to switch between them with the "switch accounts" function.
