If two versions of each application with different shebangs are
installed:
/usr/bin/foo.python3
/usr/bin/foo.python2
/usr/bin/foo -> /usr/bin/foo.python3
/usr/bin/bar.python2
/usr/bin/bar.python3
/usr/bin/bar -> /usr/bin/bar.python2

I guess, this is also possible:
Each application has a unique shebang, e.g. for /usr/bin/bar:
#! /usr/bin/python.bar
then /usr/bin/python.bar can be made to either point to /usr/bin/python
or /usr/bin/python3 using alternatives.
