At one point I planned redoing Bright Island using Cecil's code, and besides finishing it (as it's unfinished), I planned removing the Vaporwave (I didn't add it, wasn't planned), so there would have been 3 new beheaded: the commando, as it is in Revo, the Enforcer (shoots cyborg laser like Firecracker), and the Hellblazer (shoots flamethrower, explodes on death). I also often tried to do "tier 2" beheaded in my many projects, which would be conceptually upgraded versions of the base types: Gunner (rocketeer but shoots actual rockets), Shocktrooper (firecracker but shoots larva plasma), Smartbomber (throws flying bombs that follow the player like the larva, except flying), Onikaze (kamikaze that explodes into more bombs like a cluster bomb), and always had ideas for a jetpacker beheaded too.
