Too bad the variations made your idea impractical. I was laying in bed last night trying to imagine what you might have dreamt up.
There is a need for a receiver insert to use with a soft shackle that flares out to provide a radius edge for angled pulls. The problem is that the outer flared surface needs some support to protect the insert, and to prevent tearing up the receiver under high loads. If you design for a tolerable pin depth which I figure would be around 2" to make it all play nice, then you have lots of folks that can't use it with the standard 2.5" pin depth because it won't reach the hole for the hitch pin. If you make it work for standard 2.5" pin depth, then the one I see here with the 3/4" pin depth will just destroy the receiver or the insert under a high load. Just too much leverage against it not to.
I'm not going to put a product out there that requires 2 pages of exceptions listing what you can't do with it and 1 line that says what it works with. I also don't see the value in something that can't be used in most any receiver although I fully understand that no one should build a receiver with a 3/4" pin depth. The bad part is it's a US made bumper.
Possibly, if I can iron out the details. Right now I'm against a wall of stupidity I may not be able to overcome.

Edit:
It'll be pushed inward when an angled force is applied, so would a slot instead of a hole work for a varying range of depths? This assumes nothing is directly behind the receiver that this insert could push into. A wide flared face would prevent the insert from being pushed back further than the rear most face of receiver tube. A pin wouldn't technically be required other than preventing the insert from falling out during transit or a straight line pull (and securing the rope to).
It’s unfortunate that there is not a “towing” standard for this as I look forward to your solutions, perhaps a blank part that the purchaser drills to fit or you drill to their dimensions (recipe for disaster) Minimum edge distance to hole for tear out is 1.5 x bolt/pin diameter as a rule of thumb (there are exceptions), so 1/2” pin needs to be 3/4” to center from edge, so the 3/4” pin depth is not unusual for me as an Ironworker.

Original post:
What would it take to make 3 versions for the most common depths? Make a little diagram for your website like in your first post saying how to measure.
Or, so it could be used on any vehicle that needs to be recovered, a thick armored sleeve that slides over the end of the rope 4" long and thick enough to improve the radius.
What about having 2 holes drilled in the insert? One at the 1-1/4” point and the other at 2-1/2”.
