I might take the 8's if the price is right (email if interested), but the 'way' to do it would be to add a couple of leafs to your springs. I have a larger truck that way. I think the shackle raise idea will look a bit odd in my opinion. Most suspension shops will add leafs pretty readily. Our local place said "sure bring it in, we'll hook you up" when I wanted to remove a few.
