We are currently investigating on how to achieve exactly that :-)
There are two things we'd like to add:
1. a way to combine PyRun with a ZIP file which contains Python
code (this can be done by simply concatenating PyRun with the
ZIP file and adding sys.executable to sys.path)
2. adding support to compile in other Python packages into a
custom PyRun binary (this is somewhat more complicated, but
still well within range)
For both features, we'd like to auto-import a module from the
Python package when PyRun starts in this mode.
I guess we could easily do this by trying to import a special
module pyrun_startup.py in this mode. The module could then
be provided by the package and then do whatever is needed
to run the package.
Another option would be to compile in the package name
and then run "-m package" when PyRun is started in the combined

BTW: I don't think you really need PEX in such a setup. The
package put into a ZIP file and PyRun should be enough.
