In what way are you going to use those stealth servers?

If your recursive nameservers use ordinary resolution, they will never use stealth
servers.

If you point all stealth zones on your recursive servers to any servers,
they will be used in semi-random order, not as primary-backup.

If you load the zones on your recursive nameservers, they will use it
locally.
