Depends on how committed the Luftwaffe command are - at the end of the day they can bring an immediate stop to, or at least greatly reduce, the losses by simply suspending operations. If they suffer losses at a faster rate than in our timeline then I'd expect them to call off the Battle of Britain sooner and therefore balance things out. Before then any German pilots that are shot down and survive will most likely be released on France's surrender as happened.
Well if their Inteligence Section still goes for the "This are the RAF last fighters" theory they may fall for the sunken costs fallacy and keep investing good money after bad one...
