In fact this is not trivial since the force fields have not been
developed together and hence e.g. HBond lengths might be weird. You will
also have to modify force field files manually.
If you still want to pursue this, please start by making a topology for
the peptide in regular water, and then carefully merge a pol. water
topology in the peptide topology.
Before you start I'd advise you to read some recent papers from the
group of Benoit Roux.
