Two systems with the same "average kinetic energy" are not necessarily in equilibrium. Sometimes energy flows from a system with lower average kinetic energy to a system with higher average kinetic energy (eg. real gases with different degrees of freedom). Additionally "average kinetic energy" is not applicable at all to some systems, eg. ising magnet.
