No.
vbg I can't see anyway to break this loop:

You can never have too many hostnames. You can really have not enough.

Yep, just like SMTP AUTH dying.
SMTP + DNS does provide the MTA-failover with multiple MX
preferencse. But do the SMTP clients in mail programs sending mail
to SMTP servers do lookups for MX records or for A records?
If the former, then putting putting your AV box at MX 10 and Imail at
MX 20 would immunize you to AV box failing. But if the SMTP client
looks up A records, then a dead AV box kills all local clients outgoing mail.
