Although uncommon, the intentions of OP might not necessary be a design flaw. His situation is similar to C code when we export symbols, not from the library to main, but from plugin to other plugins using the RTLD_GLOBAL with the 2nd parameter to dlopen(), so plugins can have access to the symbols of one another.

OP has advanced an interesting problem. My efforts so far reveal that the problem is trivially solved by calling the functions with their full package names. It is the import mechanism of Export that fails to make things more convenient and allow us to import all symbols to both namespaces at once.
