So yeah, technically you're breaking house rules even by reinforcing the other cohorts. However given the system you're describing, I'd say that bringing along a new 1st cohort would be a little bit of a cheat on the rules you're trying to keep. Since the 1st cohort represents the core of the legion, and you want to follow the gist of the house rules, I'd say use the depletion of your 1st cohort as a flag for when you pull the legion from the front lines for refit and reinforcement.
If you're bringing out a new 1st cohort as a reinforcement unit, you're never in any realistic danger of losing the legionary eagle to an enemy...and part of the logistics LT tried to build into the gameplay was the difficulty of keeping legions fit, protected, and supplied while out on the campaign.
So, long story short, my vote is "Don't", and use it as a reason to swing your legions through home base once in a while.
If I've totally misunderstood what you're aiming at, I apologize.
