I have never done this myself so take with a pinch of salt... though I
somewhat know little bit of using shorewall and little bit about
configuring a firewall hardware.

use shorewall and modify the scripts to periodically ping the external
interfaces.. if no response is obtained within the (programmable) time
period, you switch the traffic to appropriate (failover) link.
(That's how proprietary firewalls work anyway)  and
Let shorewall do the load balancing.. while both ISP links are up...

this might be an easier approach.. than the other one...
