Please be aware that you have to make those changes within your job

You could enforce a certain mpirun by using its absolute path, e.g
"/ptmp/myname/openmpi123/ompi123_install/bin/mpirun foo" instead of
just "mpirun foo".

You should not need to delete, just add in front of MPICH.

I utterly hope I just did.

Most sincerely yours ;-)
