heh! the "sky hooks look about as I had imagined them!
They may look pretty silly but they might be a good idea. I think I would give it a go on some models. Beside looking rather strange, the biggest problem I can see using these would be an extra piece to break off on les that ideal landings.

Please don't think I belive they are something great, but they may have some merit. I am thinking of variations a little more decorative...

The only way to really test these things would be to build two identical models and have one with, the other without and fly them back to back under the same conditions.

Thanks for taking that picture and sharing with us. Preserving the plan design in CAD sounds like a decent idea.
