Outer tire wear, can it be fixed with billies at 2.5"?

So far this week I've replaced a bad wheel bearing and have 2 ball joints to do tomorrow. I've noticed that the outer edge of my new AT2's are wearing and I realize this could be due to the previous mentioned issues. But is it possible to get the camber aligned with the 5100's set at 2.5"? I don't want to get new UCA's, so if it's not possible to stop the outer wear I'll drop it down to 1.75" while everything is apart. Thanks

 

The camber should be in spec at 2.5'', it would be the caster that would be out of spec at that height (without new UCA's), and since caster wouldn't effect the tire wear you should be good.
