Having never bought any of the power core combiners before, I had a few questions, Firstly, if you bought two of the same set, could you give them identical arms and legs? eg if i bought two of the skyburst and aerialbots set, could i use two of the yellow chopper for the arms and two of the blue chopper for the leg?

also, can you chop and change differnt bots with other power core sets?
