I have a new firewall that can load balance over 2 internet connections.
My question is can I have both ISP create a PRT record for my mail server?
If only one connection has a PRT and mail goes out the other that doesn't have
a PRT then it may get bounced.

In theory yes. You can have a PTR record for every address in the ISP's subnet pointed at you if you like. :o) It is entirely up to the ISP or whoever else administers the DNS for that subnet.
