Its probably stupid, but one idea Ive been kicking around a bit is a linewide gimmick based on Transformers taking new altmodes, inspired by Shatter and Dropkick from the Bumblebee movie.
Each character would have a 'spark core' consisting of a head and a block that snaps into a transformer body, which would be interchangeable linewide. The bodies would be able to transform with the heads attached, but the cores would be swappable so that characters would take new altmodes or even switch sides.
There would be 2 size classes, deluxe with 1 core and 1 body, and leader, with either 2 normal cores or 1 normal core and 1 generic 'drone' core, and 2 bodies. The line would require a variety of altmodes, from cars, jets, and boats to beasts and bugs and dragons and dinosaurs.
Obviously, its a little close to Headmasters. The theory is that the cores have fewer parts than a Headmaster, so that the cost goes down while keeping the swapability. And swapping bodies would be highly encouraged, both on the package flavor text and in any tie-in media.
Once they got the Big 4 out of the way, they could move on to characters like Shatter and Dropkick and Drift, who have multiple altmodes, yet may not be viable triplechanger material. Beyond that, revisit other characters, such as the Rescue Bots, or create new ones. Even if a figure is an obvious body donor for an established character, there is at least some opportunity for something beyond the norm.
I don't know, in my head it sounds like a good idea, but I thought that I would put it out there and see what other Allsparkers thought.
EDIT: within WFC, set it after Unicron's defeat, and I would call it The Upgrade Wars and maybe imply that it was the battle that began the evolution of Autobot and Decepticon to Maximal and Predacon.
