This is possible and not difficult with native tools. Jim's suggestion is good. I did it with Follow Me. Although you don't have to, I started with a square and stretched it with the Move tool after getting the shape. I used an arc--could have increased the number of segments to make it smoother--for the profile. To avoid the point that would inevitably be created at the top of the arc, I put in a short horizontal line segment.

There is some unneeded geometry created by Follow Me so a quick Intersect and clean up followed by stretching it to length with Move and you're done.
