None that I know of. There are four issues:
1) are we allowed to re-distribute the Charmm forcefield with Gromacs?
2) are the functional forms of Charm ff available in Gromacs?
3) are the Charm ff files easily readable (e.g. by a conversion script)
    and do you have a (good) description of the file formats?
4) it has to be rigorously tested before you may call it something like
    'Charmm in Gromacs'...

It seems likely that many more people would be interested in this!
