No, you're misunderstanding how the rolling stock works.
An A car, for all intents is the car that always faces West, the B car is the one that always faces East, and a C car is one that is placed in between the A and B cars to make it a 3 car unit. The A car and B car are essentially the same, except facing the opposite direction.
The Mark II's didn't exist until after Vancouver ordered them. That is how all Rolling stock work. There's no "Mark III"'s, the next version is just outright called Innovia Metro 300. The Mark II's were called Innovia ART 200. Bombardier retroactively calls the Original models Innovia ART 100 in their marketing information about the Vancouver Skytrain.
Adding "C" cars to the Mark II's is probably more involved and expensive than ordering A-C-B configuration from the start. Every vehicle is made-to-order, so if the plan is to add C cars to existing A-B cars to extend the length, be it one or 3, then there is no hindrance in doing so. It's just a question of lifecycle. Why would you add a C car to cars that are already past their mid-life expectancy?
