Kdss lean, even with treaty oak spacers. Would leveling spacers help, one side?

I know the subject has been discussed a lot, but I can't find any definite threads, so bear with me.

2016 trail, previous owner lifted it, and I didn't notice the lean after I drove it home. About 1.25 inch, leans right (pax side). This is measured at both front wheel and rear wheel, so consistent on one side.

Treaty oaks spacers installed, and when engine running, and with full tank of gas, lean is down to 1/2 inch, but not gone. Half tank, and truck sitting for a while, lean back up to about 1 inch. The shocks/springs don't have a preload adjustment, so I can't mess with that. KDSS has not been cracked open to do the calibration procedure, but my understanding is that this is temporary fix anyway. Is that correct?

So, next steps? Thinking of 1/2 strut spacers on the right side, to mechanically reduce the lean.

Thoughts? Good idea/bad idea?

 

In Lexus GX460 world KDSS lean is a known problem 2010 and up. They have a warranty fix to change the front right spring. Maybe similar thing would work.

Here in CO the 2 4x4shops I go to said they fix KDSS lean by loosening the control valves. It's common problem and not a big deal.

(Edit - Oh wait, it's lifted so spring change is not an option. )
