Yeah, what I do is have all my mail virtual mail accounts stored on the primary mx, and my backup mx is configured to relay mail (only my domains) to the primary mx using transport maps. I have since introduced SPF checking in the primary, and some emails are getting rejected when mail comes from the backup mx as the SFP scripts see the IP of the backup mx.
So this sounds ok then to put the external IP of the mx in mynetwork?

Provided your backup MX has the same SMTP relay restrictions as the master MX you should be OK. I replicate our master config out to the secondaries but I have the master config set as a relay style config on the secondaries rather than a virtual delivery config as on the master.
