Risk of outage? Possibly.
I used to have a little more confidence that "concurrent" stuff could be done, well, concurrently. However I got burned on a recent firmware upgrade.
All three Power systems at the same level.
I performed the upgrade on two Power systems concurrently, with no problems.
Did the last system and had to perform an unscheduled IPL. Two lpars of VIOS, 1 of AIX and 5 of IBM i. Main production system.

But when it comes to the temp to perm firmware copy I always do that in restrictive state. But I only do that once a quarter and it's all scheduled the previous year.

The initial upgrade I did to *TEMP was disruptive. Based on your experiences, with a concurrent upgrade, I'll certainly schedule to do the *TEMP to *PERM copy in a restricted state.

Thank you. I don't mind doing things like this, but I _hate_ doing them without the experience and perspective of users like yourself.
