The most advanced simulations using ellipsoids in LAMMPS are implemented using the "MOLC" code developed by Matteo Ricci and Ottello Roscioni. It does something very similar to what you are trying to do. The paper they wrote includes their LAMMPS code, but their code lacks documentation. The paper is here. pubs.rsc.org MOLC.
