I have thought about this on and off for a very long time now. Actually I started thinking about this at the very beginning of when it dawned on me how Poomsae contained so much more than block kick punch methods of how to deal with combat. I quickly realized that the most logical way of training and teaching Poomsae was with application being taught first or at least along side the form move for move. This was later "confirmed" or at least some Karate researchers agreed with me (Patrick Mcarthy for instance) that Kata was taught after the applications had been mastered, as a way to remember them and as a solo excersise format. I have sometimes thought that if I ever get to "master level" (that would be 4th Dan in my org) I should start my own Dojang or perhaps take much more responsibility in the one I currently train and study in, and one thing I was wondering was if I should revamp the way we teach Poomsae. I have shared the way I view Taegeuk Il Jang quite extensively so my future students could in theory learn at least one "good" application for each move in the Poomsae with partner drills and live testing of some if not all applications very soon after they started training.
