One thing that I've seen done is providing bonuses on saving throws to resist fatigue at odd levels. You could also do something with armor familiarity. For example:
1.) Armor familiarity I: reduces check penalties by one, 1/2 time required to don/take off while in light armor.
2.) Armor familiarity II: reduces check penalties by two, 1/2 time required to don/take off while in light or medium armor.
3.) Armor familiarity III: reduces check penalties by three, 1/2 time required to don/take off while in light, medium or heavy armor.
--just a thought-
