Kind of yes, and kind of “why not?" ;-)

This is what is already done by the AppImage, except that the mound directory 
is generated with a temporary name, different each time. This is not something 
under my control, and what is causing trouble in this specific case...

Not wanting to starting some Linux "wars" :), I think of AppImage as
Linux's acknowledgement to Mac OSX Apps.

So in that vein, include a launcher in your AppImage which mounts your
support libs is a specific location (possibly /tmp) and then point the
python interpreter to something like /tmp/python/python or something
similar.

Maybe that will work?
