I don't think this is possible without major code overhaul. Amoeba uses
as buffered 14-7 term for nonbonded interactions, whereas OPLSAA uses
as 12-6 potential. Amber doesn't have any ability to handle such mixed
nonbonded potentials.
You might try Tinker itself, but what you want to do sounds very hard:
are you sure you will learn something from such an odd combination?
