Nice idea Rakayados, except for the cost, because a gyro stabilization cockpit is an integral part of B-Wings, like adaptatives ailerons on TIE Strickers. So this upgrade should be free in my opinion.
You may add : "when you perform a barrel roll action or a red maneuver with at least one stress token, roll one attack dice for each stress token you have : on a critical hit result, discard this upgrade and loose your barel roll action."
Because, according to Wookieepedia, "the gyro-mechanisms for the fighter were prone to in-flight failure, causing the fighters to end up "frozen" into position, thus leading to maneuvering problems."
