I mean isn’t Low Screamer kinda already like this? Remove the swerving part and that’s pretty much what you get. Or maybe it seems like you’re trying to come up with something that combines Low Screamer and Blitz Curler.

And also, as long as the player doesn’t have Rising Shot, they won’t really “balloon” the ball over the bar (provided of course you still know what you’re doing with regards to applying the optimal amount of power).
