Are you, at that point, not adding something far more complex and big then 'just adding more cells' ?
Technically yes. As my idea with downward exhaust seem to be failed, i'm looking for a place to add some more cells, so that any flight deck operations wouldn't deny the ability to launch missiles. However, it seems, that I need to redo the entire superstucture to free some space on deck. So currently I'm looking for different supersteucture options.
