OK, I can visualize what you mean, but all that will do, is change a circular motion (btw which also induces centrifugal force in a sprinkler) into one with the water, where no part moves, so you're basically using this force to "bend" the straight flow into what I call a "near straight" line.
The faster the flow, the more "bend" there will be, from the straight line, but there will be no swirl: i predict less than 1/4 turn, probably 1/8.
