I think that your idea stands to reason. This plot will work together, and I believe that everything will tolerate acidic soil, but will be forgiving should it go alkaline. And yes, you are correct. Blue will be on the acidic side. Just try not to go below 5. This can be dangerous for all but the hydrangeas.
