Yeah, I won't tease you about the E2 vs 4pt thing. :-)
I'm not a fan of people using suspension mods as a replacement for a WDH, but that's not the case here. Just be sure that when you do your WDH adjustments, deflate the air bags (or whatever they are) so you get the hitch right.
Remember, you want enough weight distribution so that the front wheel well height with WDH engaged, is the same as it was before you attached the trailer to the ball. If the wheel well is higher than stock, you need more weight transfer.
Going 2 spaces down seems excessive to me. I'd start with only 1 slot down (which will be 1.25".
