Not crazy at all my friend! I already used it in my Battlecruiser, it is a little bit glitchy but it works, it is a giant invisible box around the ship that sometimes withstands several tactical nukes and sometimes allows a TU-95 rear turret to destroy everything hahaha, anyways I don't fully understand the damage mechanics of the game.
Also, good news everybody! The carrier take off at 1000 meters of altitude works! I haven't try landing since the BC-304 has a little design failure... there is no back door to the hangar bay, you have to land from the front, I don't know how AI handle this... Here is some pictures of 16 F-302 taking off from both hangar bays! I used another invisibilty trick, the collision mesh for both decks extends way beyond the hangar bay so the planes have more distance to accelerate or land.
