I wonder if you could create a fourth bridge and connect your monitoring system to that. Then, I think you could create a patch port that is the mirror target in each bridge and have the other end of each patch port plug into that fourth bridge. You might need to modify that bridge's flow table to direct traffic into the monitoring system's port, since if you wouldn't want mac learning to happen. I haven't tried it, but it works in my head. :-)
