Setting up HA for multiple DMZs using trunks.

Greetings everyone.  First time poster.  After some quick searches and not finding quite what we are trying to do I decided to try the forums.

Our goal is to setup two LM-5300s in a HA configuration to load balance for multiple DMZs. Here are two diagrams showing basic logical and L3 layouts


L3 layout



Each DMZ uses the firewall as the gateway for all inbound and outbound traffic.  Can the 5300s be setup as multiple one-armed LBs using trunks (and bonds)?  If not, can the 5300s be setup in DMZ2 and serve as a LB for DMZ2 as well as the other DMZs?

Thank you.
