Should be "importing_module_from_dlls".

It will work if handled by the zip importer.
As for ARCHIVES directory: a "virtual" path for all zip files could be =
built for lookup.
Importing from __init__.py could be done explicitly with:
from MyArchive_with_many_modules import MyModule
or
import MyArchive_with_many_modules.MyModule
where MyArchive_with_many_modules is MyArchive_with_many_modules.zip=20
in the same directory (or in ARCHIVES)
