the sharkticons are transformers of a sort, so I'd love transforming toys of them.
the quintessons on the other hand, appear to be organic in a metallic carapace/armour, they aren't transformers as such and a quinteson toy that transformed would essentially be a non-canon toy.
It's like a transformers/marvel or transformers/starwars crossover in my mind they occupy their own universe, anakin isn't a transformer and his representation as a starfighter is just odd, in the context of transformers or star wars.
It's like having a starship enterprise that transformed into a kirk or picard.
a quintesson with excellent paint, sharp mold design and articulated tentacles, and maybe a light tower/stand gimmick would appeal to me a lot more than a quintesson that transformed into a bipedal robot, or a random space cruiser.
