I still think what i suggested is the best option for robin. technically the only difference in RG and JT is hair when behind the mask. to have hair options instead of batman's expression mouth pieces could optimize the heads. the tim drake head and costume and accessories being a exclusive so if you want time drake you have to buy it. Making it one boxed figure saves sideshow time and money making multiple robin's and maximizing sales. by making them separate makes them less money over all. there a company interested in making money it's just a smart choice.
I know you may think they would make money by making separate figures but that cost more money. the box, body costume advertisement etc. when they only have to do all of it once. there sales of han solo hoth probably proves my point im sure they agree with me, they would have made more just adding the alt suit to box.
It's what i would do if i was in there shoes, it would save them time to move onto another dc character. you guys talk about things like they are going to keep this license for 1/6 indefinitely it cost them to do that i don't know how much it cost for contract for how long and renewal cost if any, if there allowed if they cant make it all in specified time.. but endless time which really is not the case. it's bad enough they slowed down to make the black and grey suit. this might hurt them with sales. and i hope this doesn't discourage them to stop. you can say im wrong and im cool with it but im most likely right about the sales of this.
With Batgirl they can't go wrong just stick with Babs as the others were short lived
