That's because it is a cheap fix. I don't like external chainplates on any boat, but if I saw them on a boat that wasn't designed with them I would walk away.
The major problem with moving to external chainplates is that they have a larger failure area than on penetrating ones, and are covered in salt water much more commonly.
It really concerns me that people constantly want to mess with the work of a professional NA in such a substantial way without checking with a qualified expert. Swapping around chainplate locations is like moving around the structual walls of your house. Sure it might be ok, but it wouldn't do it without checking with an architect.
