Hm, just wanted to mention those ideas...
For ships with only a few turrets (<=5) , I found that X2's 6-monitor-view works pretty well

.
Of course, on larger ships, that wouldn't really work...
So, for larger ships I'd suggest an additional interface that's more like that of RTS-games:
1) in the loadout screen, give the player the possibility to group his turrets into Ctrl-groups just like units in an RTS, and also select one turret for each group that would be used for such a monitor-view like in X2.
2) in-game, the player should be able to a) give orders to those groups via the com-system
and eventually b) reassign turrets to other groups, propably also using the com-system
and of course c) take over control of one of those groups, maybe also using the com-system (or then, maybe some keybinding would suffice for this one)
and d) change the target priorities of those groups, again via the com-system
Though, of course, a giant additional dropdown-list instead of the com-system would also work... but that'd block your view.
Though, if you could switch to it with a keypress like homeworlds' sensors-screen, the list would have the advantage of being mouse-controlable, and you could also show some info on what each turret is doing...
So, any comments/ideas/whatever ?
