Historically the Wehrmacht set up a strategic education academy for the best, brightest, older, and more experienced staff officers of the three services in 1935. It offered a 12 month joint strategic education program for 10 students per year, 6 from the Army and 2 each from the Luftwaffe and Navy. Not only would the students gain education about strategy and war economics, but have the benefit of being educated about the other branches they would work with, plus actually study and work with the future and current leaders of the other branches, developing relationships which would carry over to actual planning in wartime. There men were also expected to serve at OKW at some point too and all were graduates at the top of their classes in their respective branches' higher education academies. Historically many of the very best of the Luftwaffe attended, including 4 important generals (later CoS Korten, von Rhoden, Kreipe, and Schwabedisen).
Also historically Wever and von Blomberg were major proponents of the Academy, which was the brainchild of von Reichenau, but was opposed by Goering as a threat to his power (he did not want a unified military command for the same reason). Still by 1938 when its last supporter was removed from power (blomberg), Hitler had OKW, but the school was closed because of Goering's machinations. What if the school had been kept open so that more of Germany's staff officers had gotten the apparently excellent strategic education that it offered? The major criticism of the Wehrmacht was their lack of understanding of and education in strategy in WW2. Of course Goering is going to be against it and Hitler generally chose OKW officers because of their loyalty and pliability, rather than competence, but nevertheless of the officers that graduated went on to be important staff officers or leaders within their respective services.
What effects if any would there be to keeping the academy open from 1935-45?
