Acoustic Build: Tonewood Issue??

I'm a little concerned with my Walnut back that I recently purchased and thought I'd ask if it's a big deal.

The wood is beautiful with great figure and a hint of sapwood showing at the seam. The only issue that I have is that the 2 plates are slightly bent from end to end which isn't a big deal, but they are bent in opposing directions. So, for example when I lay them on top of each other with both "outside" faces facing upwards, I get a shape like this --> )( where my spruce top is very nice and flat and stacks perfectly flat --> ||

I tried clamping the plates on my gobar deck + with cam clamps for 24 hours with no luck. I just worry that when I go to glue the plates together, they will really resist and I will have a difficult time making contact at the seam as the right plate curves in a slight "U" shape while the left plate is slightly curved downwards in the same shape.

I'm just wondering if this is going to be an issue as I've generally only seen very flat tonewoods for building. Thanks for any advice.
