Yeah unfortunately I don’t think such tech exists and at our current tech level I wouldn’t imagine it would work and could present real safety issues - you’d have fuel pipelines running throughout the airframe which is likely a significant amount of really serious fire risk, all of this adds a significant amount of weight and maintenance cost, I don’t believe such adjustment thrusters exist but I could be wrong, and I’m sure you would still get things wrong in your prediction which means your thrusters would add wear and tear on the airframe as well.

This article is about a PoC where they put sensors extended out of the airframe of a small slow moving aircraft and demonstrated a 60% prediction accuracy for a 10% fuel savings. It’s unlikely this approach would scale up to an airliner. The sensor problem might be but I have big questions about the adjustments an airliner moving at 600-900 mph can make to successfully counteract the prediction.
