Here is what Kanan’s card does for reference. I was just curious if after using Kanan’s ability, if the chosen ship that’s stress was removed would be allowed to perform an action if they no longer have stress.

Yes

"1. Reveal Dial: The ship’s assigned dial is revealed by flipping it faceup
and then placing it next to its ship card.
2. Execute Maneuver: The ship executes the maneuver selected on the
revealed dial.
3. Perform Action: The ship may perform one action."- rules reference page 3

So the execute maneuver is separate from the preform action, so after you fully execute a maneuver you do anything that happens after that, then you move on to perform action.

I'll add: because Kanan happens after step #2, while the stress from a Debris Clout happens within step #2, Kanan (as in 1e) allows a ship to fly through a Debris with a white move, clear the stress, and still take perform their normal action. Well, you have to not-bump, but still.

Thanks for the answers, glad to know he works the way I hoped he would!
