Peach tree guild & blueberries. PNW zone 9A

Thanks for the post about tree guilds. I hadn’t considered that before. I plan to take out the rose bush in the spring and plant a frost peach. I did an urban garden tour and found out a neighbour a short walk away got 50 pounds of peaches from a small tree in a similar spot. I was planning on planting the two blueberry bushes in the ground since the plastic tubs are cracking. Will thr blueberries preference for acidic soil work T with a peach nearby? Also can anyone suggest good companion plants? I am planning to sheet mulch more area in front of the roses and blueberries.Thanks.
