Just thinking through this, but if it's an entirely separate environment, just host it on a separate subdomain and the account id becomes irrelevant. If you have a functioning staging environment, you already have the ability to run an isolated environment without issue, this is just a different application of the same idea.

You can probably run the environment itself, but other systems (release management, monitoring, billing, etc) probably rely on the account_id being unique.
