If you have gone to the trouble of making such a precise drawing, you are already 90 percent of the way to success, IMHO. My only question is how do you intend to keep the fence parallel to the blade for the saw? This is not so much a problem for the router as it is a rotary point, but the saw blade must be very closely aligned to the fence or you may get binding which can be very dangerous and cause kickback. If you have a solution for this, great...I just didn't see it in the drawing.
Woodworking is more than a hobby.
It is a journey of discovery,
An application of innovation and creativity,
And an opportunity at self improvement.
