I am not sure that OOO and Fran's can (easily) work together, without installing FCOM.
FCOM does indeed require MMM, but it does not require OWC. Nor Fran's, for that matter - not that that fact will be much use to you, it would seem.
edit: In case you are not already aware, MMM is
highly configurable - for example, if there are creatures you do not want in your game, you can probably disallow them, with a plugin. Likewise, if the spawning is too "full on". And so it goes with FCOM.
