Bilstien 6112 with OME-60100 rear and Valley spring AAL

I have the 6112 up front at 1.9 and plan to raise it to 2.5 when I do the rear. In the rear I am planning on getting a custom add a leaf from valley spring shop in Phoenix,AZ. They offered to re-shape my factory rear leaf spring pack since I overloaded my payload with some dirt and fear I may have flattened them a little. They are also going to add 3 new leafs to the stock spring pack to add 1.5" of lift, give it a progressive profile, and add close to 1k to the payload. They are going to rebuild the whole pack as one which apparently should help with longevity of the pack. Since the rear will be progressive now I figured I would also add a progressive shock like the OME-60100. I originally wanted the 5160's but feel like it's a bad idea to mix different shock profiles on the same suspension component. I would also be maxing them out to 1.5" of lift, which I feel is bad as well. Would this be a wired combo to have digressive up front and progressive out back? Could I mix the digressive 5160s with the progressive spring pack?

 

I’m not sure about the other aspects of this post, but I do know 5160s can be run up to 2inches of rear lift.
