In the review thread for PCC Heavytread it was discussed how similar looking he is to Brawl, which got me thinking that with some modifications, he might be able to make a suitable replacement for the tank limb from the Bruticus Maximus set. Judging by the video reviews of him, he should even be able to adopt a G1 Brawl leg configuration pretty easily, plus it might even be possible to swap out the combined mode head for some kind of connector port. Along with the Crossfire set from Fansprojects, it would help make an even more G1 accurate Combaticon set. Plus, some mods to the Searchlight mold and you might even be able to make a more G1 looking Vortex as well, then you could replace all the original Bruticus Maximus limbs! I don't really know how feasible such an endeavour would be, as I don't have the Crossfire set or the necessary PCC molds, but perhaps someone could do something with the idea?
