This does seem like it should function the way you would like with the exception of the health monitor. Keep in mind that with that monitor you're only monitoring the interface on the firewall rather than the connection from the firewall to the ISP so if routing is not functioning between the firewall and the ISP or the ISP has any routing issues that will not be detected.
Since it's a transparent monitor, wouldn't the health monitor be checking the reachability from the F5's self IP via each ISP router to Google's public DNS server (8.8.8.8) and hence, this would verify that traffic using each ISP was working?

I believe you're right but it's always possible that you can still have an issue on that ISP and that singular destination is accessible but other destinations are not. Thank you for the correction, I missed that piece in the health monitor pointing to the other destination.
