Not only that, it already existed (albeit for slightly different design purpose) on the KC-46.

Then when flight tests show your aero modelling was deficient, make it four times more powerful to compensate.
Job done, plane certified. Cease panic. Aaaaannnnd breathe. Now quietly collect bonus and run before the s
