You could run GB with OPLS, but the GB parameters have not been optimized
for this (especially not tested at all for united-atom carbons), so I don't
think the results would be very good.
Also, please remember that the OPLS force field files in the Amber
distribution are about 10 years old. The newer OPLS/AA force field parameters
have not (yet?) been coverted to Amber.
