Or do you just keep the same lineup?

Are you even made aware of the event?
Nothing has ever happened to alert me to the Marius reforms taking place when playing as another faction, I only found out through suddenly coming up against legionary cohorts.
One slightly strange thing is that if you are playing as Seleucids, Armenia or Numidia, and you tech up quickly, it's possible to recruit legionary cohorts (supposedly modelled on the Roman originals) before the Romans can!
