I've given up playing computer games for Lent, so my fun for the evening has been diagramming my plans to redo the hetairoi in-game. I think I've figured out how to replace most of the existing units with Spirit of Rob's hetairoi (which are generally better-looking), make some units more historically accurate (e.g., turning the Bactrian Hetairoi into Iranian cavalry, which is really what they are), and still end up saving one DMB slot.
Yeah, my life is pretty boring right now.
