ive actually thought about this. You honestly could grind off about 1/4 inch and they would clear, and there is plenty of strength that would be left.

I have gotten pretty tired of dealing with this honestly. I still wonder if the readylift bump stops would work

 

I see the bumpstops as more of a bandaid to a bigger issue. The truck is lifted by compressing the existing suspension, so we need that extra downward travel to compensate. The only real solution I see, are UCAs that clear the upper coil bucket. The search is on.
