AFAIK this would work at the system level. I have experimented with using
ligatures and not had any problems. However (an unrelated problem), you
would have problems with most applications as they do not handle plane 1
characters correctly (even most of Microsoft's applications until Office XP).

Of course, if you are planning to develop keyboard layouts for new versions
of Windows, you should probably be using the Text Services Framework rather
than the legacy keyboard DLLs.
