Well the only Concentration needed is a few Force Powers, not all of them. I think that is fine and fits a bit as a disadvantage that Jedi (and other Force Users) have to worry about that non-Force users don't...
How about for the feat the following...
First Aid, Prerequisite: Medicine Skill Proficiency. This feat allows a character to use their Action to attempt a Wisdom (Medicine) check on behalf of a creature afflicted with the Reeling or Stunned Condition. The check must meet or exceed the Reeling DC to succeed. A successful check removes either condition (character's choice). If the character exceeds the DC by +5 he instead removes both conditions (if the creatures is suffering from both).
