This will rely to a great extent on doing something about #63365.

server: add temporary COCKROACH_MR_SYSTEM_DATABASE option
e1c6728 
Add an environment variable to enable non-backwards compatible changes
made for cockroachdb#85612. This variable is temporary and will eventually be
replaced by version gates. The COCKROACH_MR_SYSTEM_DATABASE option is
only safe to set before the tenant cluster is created. Setting it after
tenant cluster creation may lead to corruption.
