Interesting on the actual pic that nosecone has the Decepticon insignia on him, that is clearly takaras groove prototype and lightspeed is clearly just smokescreen given the numbers. Must be an early prototype shot. Just shows how little effort it takes when the retool
The sensible thing is to do up a cheap mockup to see if the idea will work or even get approval from the bosses or bean-counters, so this was probably the very first physical concept proposal, thrown together with existing toys and prototype parts/toys. Judging by the grey Groove prototype being used, you can probably work out the rough time-frame this proposal idea was whipped together at the Hasbro offices.
