In what possible way is that a solution to anything the OP has brought up?
Some are more separate than that; for example, the British and American keyboards are quite different, and as has been mentioned so are the French and Quebecois. Spanish actually has a lot less versions than one would guess from the list you can see in Windows, which makes it look as if we have a different version per country plus the international one (the difference between the international and reduced keyboards is one key).
Still: I was in a project in which neither we nor IT could change the keyboard layout on the desktops we’d been assigned for the English-speaking location. Since we needed to write documents in both English and Spanish (the mother ship was a Spanish company), we were able to use the lack of an ñ key as an excuse to use our much-faster laptops… but seriously, WTF with not letting people change keyboard layout, in a company with employees from two dozen countries?
