Glojo,
Simple stuff for me.
12 jets would probably give you a 26 sortie day in peacetime. They would come crewed about 2:1 with a small overhead of scamps that were good for not much - so let's say 27 FW aircrew flying a 8/6/6/6 cycle which would take about 14 hours from first engine lit to last one stop cocked.
That's pretty much all your supervisory chain could cope with in peacetime so no real need to uplift anyone other than for hostilities at which point, yes, you might have to drag some extra bodies on from somewhere.
That is, of course, assuming that there were some more jets to uplift or 24 hour ops were called for.
Probably grossly out with my asumptions - which are actually slightly informed wild a##e guesses.
