I'm anxious to see other responses, because I'm trying to do something
very similar. In the meanwhile, though, there are two suggestions I can
make:

First, depending on the content for what are now subdocuments, you might
be able to use autotext entries. While they are generally menu-driven,
you could probably use radio button controls and VBA instead; that's out
of my expertise.

Second, the best way for you to do what you want is really with a
document assembly program. HotDocs is the only one I'm familiar with,
and it works nicely with Word; there are others, too.
