It's not clear you can use a common "resources" file. You need to copy
the namespaces represented by each module into separate namespaces in
the file you're going to import. Multiple files can do this, but there
may be another approach.

Yeah, it's viable. LISP has been doing it for quite a while.

However, note that you have to figure out what objects in each module
are needed in each function you call from that module, and recursively
examine each of those objects. It's a non-trivial thing to do, and
will rely heavily on introspection of the objects in question.
