I've seen wheel spacers be successfully dd'ed. Have you ever had a lug but work itself loose? I haven't.
3" should be pretty easy to pull off for you. My 4.5" drives great with adjustable upper arms and an sye. The t case drop was decent but at 3" I'm sure it's fine.
I've also yet to have a jeep aligned at a shop. Measuring tape always worked for me.
