Robert,
How many servo's will the Weeks have? Is the Weeks a Biplane? Will it have a servo for each ailerons? The total number of servos and the number of channels on your transmitter has will determine whether or not you can eliminate the Y-harnesses. If you don't want to use Y-harnesses, both Futaba and JR make matchboxes so one channel can control more than one servo. They are very nice and work extremely well, but they are not cheap.
Fly safe and have fun!!!
