So I'm just noting alpha the hovercraft move as a unit so all of them would be under an lb-x umbrella meaning your planes and choppers would be at risk if you tried it.
Doesn't mean I won't risk it, I can still make it a difficult shot and its unlikely a few LBX will bring me down if I have 4/4s in the cockpit.
Suggestion (that I would never use but you can) something like this would be pretty dangerous

Now based on my understanding of how C3 works (and its weird) the Itano can link with the Masters of two Heatwaves and three other units (likely the Hailstorms). Each Heatwave can in turn link to a Whirlwind and two spotters and enable fire from any unit connected to the network. So you have potentially 70 (possibly semi-guided) LRMs or 90 MRMs dropping in per network. If supported by say a roving fireteam of 4 Regulator A4s you can add additional Artillery (and/or Air Defense).
All while being much cheaper and mostly better defended.
