At the risk of reducing game complexity, reduce the number of thrusters, and allow them to be picked up and repositioned? or if you want to keep the current system of a ton of single-placement thrusters, allow turning off and on?
actually, i really like the first idea, that can improve the performance issues late game, and make the map clearer without hurting the idea of moving around with thrusters, and late game i often have like 100+ thrusters and they are useless, bad progression design honestly
