I'm no kit designer, but I would think that most of the design work (assumming it was done on CAD) would remain the same. I'm sure going down from a 46% bird to a 33% or even a 27% one would require some re-engineering here and there.

Even if there is a little re-engineering, as long as the color scheme is retained they would sell a ton of them. What a beauty!
Besides, isn't that what they do?.....design and build planes....
