How do you feel about duocons? The original two duocons weren't anything out of the ordinary in design, but I've always liked the idea. I guess Armada Tidal Wave has some elements from this too. I think Transformers that separate into two or more vehicles could be a neat idea; maybe if they had a subline (Think PCC) of scouts/deluxes that do this? It could be a neat idea and you could still combine torsos with legs. It's less complicated to design a transformation when it doesn't have to conceal both legs and arms in the same vehicle so it wouldn't imply extra work per figure. I think this could have potential. If well done, would such a subline interest you?
