That would have been good, but bear in mind the original PC wasn't
designed to be scalable at all. The fact that the industry decided to
adopt it as a de-facto standard was stupidity on the part of the
industry, not IBM. (not trying to defend IBM here, but this is just
the way it is)
I think they did a very good job for a cheap "throwaway" design done
by junior engineers. The production cost of the PC was almost nothing;
there are exactly *zero* components on the original PC motherboard
design that were more than a few dollars apiece.
