Will all of the wing ribs have the built up structure? If the ribs were just cut from sheet I would suggest the old RCM wing jig. A wing jig needn't be expensive in money. You will have to do some geometry but you can calculate the amount needed to raise the trailing edge of the outermost rib to get the desired washout. From there you can cut a triangle shaped brace, the length of which is the span of the wing panel. The tip will be 2 degrees high and the root will be at 0 degrees. Your wing spars should help to hold everything in alignment.
