If we could get a drone with PowerFLARM

good except for the pipeline patrol guy.

Would take a bit more time to retrieve the rope, but an wheel rim on a shaft on top of a fence topping frame would probably work if done properly, though a gate would be better and much more desireable. Retrieve drivers would have to be able to drive in a straight line. Not too hard on a flat surface.

There was a club that reportedly used a wheel rim of some sort on a post to guide the rope around a runway dogleg during the start of the launch. It may have been in the UK.
