@invalidusername As a long time user of Diamond hot ends, I'd say that you've made the right decision. I know very little about Deltas, and I have seen Diamond hot ends mounted to them (albeit not water cooled) but these are still seriously heavy beasts and 5 Bowden tubes or flex shafts trying to pull an effector in all directions would be a concern I would have thought (but I know very little about Deltas so might be wrong).
