I sure wish I had your collection of planes! Don’t worry about buying materials for the stringers, I just realized I need to go buy some for stringers myself. I haven’t decided what material yet tho but I am thinking to match the legs, Red Oak. I just finished the design and have laid a few things out, I may start a bog as well but don’t have near as much skill as you.
