That's the Val, the Kate, the Peggy.
Now we need the Boston, A20G, Ju88, Me163, Tempest, and Ar234B
That's a pretty short list! We're getting there! I say the A20/Boston will take the most time because of the internal spaces. The Ar-234B needs changes (no rear guns, period, but option for a forward pair in gunpod) The 163 and Tempest will probably be the fastest to update based on relative size and geometry of the models.
