what are the chances of adding an option for the skull to replace the body of the Spidertrons as well asking as A the companion drones use the body sprite normally and B it would look super neat to have all my 'drones' have a cohesive look

Option for the skull to replace the body of spidertron: Nope, wouldn't look good. Especially with the legs

Companion drones to use the body sprite normally: Uhh, don't quite know what you mean with that

Cohesive drone look: What do you mean by that? / Please elaborate

Companion drones to use the body sprite normally: Uhh, don't quite know what you mean with that:
the Drones of the Klonans Companion Drones mod use the body assets of the Spidertron minus the legs and a small flame out the bottom of the model/sprite

Cohesive drone look: What do you mean by that? / Please elaborate:
to have all my bots, Spidertrons, and Companion drones all look the same way

Option for the skull to replace the body of spidertron: Nope, wouldn't look good. Especially with the legs:
i tend to disagree there i think it will look awesome
