Would it be feasible to build a fully RFC 1925 (6a) [1] compliant
solution?

(1)
Have a supermaster SM run from Oracle

(2)
Have a single superslave SS run against the supermaster, replicating
via DNS

(3)
Have SS run against a MySQL backend which does MySQL replication to
your normal slaves NS1 up to NSx.

That way, you only have to clean up one superslave, and you don't
"depend" on MySQL as you can easily replace the MySQL setup with any
other replication mechanismus including something resembling your
existing supermaster/superslave setup without having to touch the
Oracle - SM setup.
