3P, if you find this, screw it, just steal my idea: For the toy, don't bother trying to actually make him into a triple/quadruple changer. You're not going to be able to make enough people happy. Focus on the fact that he has 2 robot modes and exploit that. Aircraft Carrier Mode Jet Mode Robot 1 Mode Robot 2 Mode So, where can we look at for reference on doing such a thing successfully? First, we have Siege/ER/Kingdom Ultra Magnus. A king of partforming and also having ulfolding panels. Studio Cell and HasLab Unicron are also great examples. You have a large Alt Mode with lots of panels. One successfully hides them, the other folds them down a lot because it's mostly just a big shell. Secondly, and this is the major part where we can exploit the 2 bot modes (optionally), look at the Power of the Primes leaders. Orion Pax/Optimus, Hot Rod/Rodimus, these are figures that incorporate multiple Robot forms (1 small, 1 large) that combine into a large alt mode, and can separate and have a smaller/less complete alt mode. So... Robot 1, would be around Springer's size, and would need to actually be capable of either a lot of forms (Robot, Jet, being part of the ship, and being part of the large robot), or simply having parts attach to it like the aforementioned Ultra Magnus. Robot 2, or maybe just "shell/docking station for robot 1" or even "armor parts for robot 1" would make up the bulk of the ship and the bulk of the Combiner-sized variant of Broadside. Accessories: Miniature Jets for Carrier Mode (one could even be Broadside himself ), that could form together to make a weapon? TL;dr: Broadside can be successfully accomplished by avoiding the idea that you need to make him a single robot.
