I think you might be making it harder than it is? It sounds like you can probably just customize the 1 Mapped Key in ISB42 - Combast Broadcast. (i.e. have it send something to the inquisitor, and something to the marauder, instead of the same thing to all) If you're doing this for different characters on the same team, you do not need extra Key Maps etc.
If you are duplicating Combat Broadcast -- which again I would not do if you're looking to have something different happen on different characters in the same team -- you do not need a new Combat Broadcast Hotkeys, or Menus, toggles, new entries on Activate Maps, etc. If you're looking to do different things depending on your Character Set, then you can just duplicate ISB42 - Combat Broadcast, and set Key Map Virtualization at the Character Set level alongside the ones the Quick Setup Wizard makes (similar to the way the Pro Configuration suggests virtualizing per-Character).
