I don't think the idea of tape, lead, or a nylon tube will work. There's not that much clearance between the hook and the inside of the eye.

I think it is what was said, that the swivels were meant for carrying to a stand and then removed. That limits the usefulness of a sling. But as I said, they are absolutely "proper" so we must use them without complaint.

Mike, have you ever made any stab crimpers? I would like to find one for a Henry .450 BPE.
