did you compare the quality of the structure calculated with modeller with that of the template(s)? If the quality of the model is really worse something might be wrong with your alignment. Did you do the manual adjustment of the input alignment on basis of the analysis of the quality of the first models? This usually helps a lot. I do not think that it is necessary to use charmm or another external molecular mechanics package to improve the quality of your model. Modeller actually uses (an older version of) the charmm force field for the molecular mechanics part of the optimization.
