Using/converting old extended top and par files?

Dear NAMD users

  Does anyone know of a way to convert "explicit hydrogen" type
parameter and topology files into the all-hydrogen format, or somehow
use the files to deduce information by hand?

  I want to simulate some modified RNA fragments, and many of the
modifications are accounted for in the toprna10r_22.inp and
pardna10_22.inp files found in the latest charmm toppar release as they
incluce tRNA modifications. Somehow converting or extrapolating from
those would save a lot of parametrization work.
