Hard to tell, but the B-pillar of your design seems to be quite slim, so maybe the A-pillar actually has to be
stronger, than usual. One problem with those minivans is, to my opinion, that due to the higher ceiling,you
are seated quite far away from the forward windscreen edge, so the panoramic effect of the curved windscreen
gets lost. And it's hard, to wipe the inner side ! Of course, blower and air-condition should make this unnecessary,
but it still takes quite a lot of time, so a rag still is the faster solution .. as long, as your seat-belt isn't fastened.
Don't worry about the similarity to the Zafira. Ours is silver coloured, so coming back into the garage, you generally
sea dozens of cars, that look like ours ...
