As update to the group, I made a move!
I brought the conversation and cables to our fab shop. An extremely talented fab guy said, "I can narrow those spade legs without breaking them and get to an outer spade dimension of 7/16". I thought, go for it, he’s confident he can do it and I know he’s good at what he does. I’ll just have him do one and then show me. And BTW, Clarus did say they would repair/restore a mishap if I have one.
Well, IT WORKED BEAUTIFULLY! The spades are now 7/16" with legs about 1/8". I expect they will fit onto the Vandersteen Barrier strip when I bring them home, and the screw down will have as much contact with this modified spade as it would have had it not been altered.
So, happy ending here. Most importantly though, I want to thank everyone who participated and provided me great options.
I’m very tankful and grateful!
