Well, you can't "split" on badlines. You can skip badlines, but then you need to change charset for the next character row to show different graphics there, so that's doable.
BUT, you can't hide the firs and last character of the scroller like you do using 38 wide screen. Maybe you can fade out colors, but I agree, it will be ugly.
Still, I think it is possible, but a much more complex exercise and no hardware trick is involved. I think you need something similar to what MC did in Autumn Colors' vertical scroller. He used a clever charset for the task.
