I think there isn't enough room for all of that on the ribbon. I could be wrong, never myself had to put that many devices on one ribbon actually. I know the OLC's that come with 4 together are a little more compact than having to put 4 individual ones on there. That might allow enough room to get them all on there.
The graphics I posted are right from the EZ rackbuilder site when I tried to build a rack with 5 ARCOMS and a V device.
