Is it possible to have type hints in a separate folder within the same project?

I'm adding type annotations to a package I maintain. According to PEP484 stub files for type annotation (.pyi) can either be distributed alongside the actual code in the same directory or in a third-party package. Having the .pyi files in the same directory, however, seems inelegant and I would much prefer to have them separated; similar to how this is done for headers and implementations in C/C++.

In a nutshell, my current package structure is something like this:

my_project
|   setup.py
|   pyproject.toml
|   ...
|
|___my_package
|   |   __init__.py
|   |___module_1
|   |   |   __init.py
|   |   |   fancy_module.py
|   |   |   fancy_module.pyi
|   |   |   ...
|   |
|   |___module_2
|   |   |   __init__.py
|   |   |   more_files.py
|   |   |   more_files.pyi
|   |   |   ...

and I would like it to be something like this (with type annotations supported by mypy and vscode at least):

my_project
|   setup.py
|   pyproject.toml
|   ...
|
|___my_package
|   |   __init__.py
|   |
|   |___module_1
|   |   |   __init.py
|   |   |   fancy_module.py
|   |   |   ...
|   |
|   |___module_2
|   |   |   __init__.py
|   |   |   more_files.py
|   |   |   ...
|
|___stubs
|   |___module1
|   |   |   fancy_module.pyi
|   |   |   ...
|   |
|   |___module2
|   |   |   more_files.pyi
|   |   |   ...
  

Is this possible or do I need to look into distributing a separate "third-party" package?
