Well, this does cause problems for any Masterpiece Meister that might come along. I don't think TakaraTomy would like to fudge the alt mode of such an iconic character. They'd sooner just not make one.
Like most of the G1 pieces (ie prime was a freightliner cabover now a peterbuilt conventional) instead of using the latest model they are changing to different MFG. as far a nostaliga I personally think this sucks, Jazz will always be a porsche, bee a bug, prime a cabover etc...
