Unless you want to try to hand-edit the prmtop file itself (which is certainly
feasible), you need to make a new prmtop file (say, using a new frcmod file)
if you want the parameters to change. The sander program only looks at what
is in the prmtop file, and doesn't know anything about frcmod files.
