If you have the resouces and want to build a transmission, I'd say go for it, but, especially if you plan on using only drill motors for your drive, you can do very well by simply using the drill transmissions and shifting them with servos or, better yet, small pneumatic cylinders. Another option is using the drill transmissions with an extra motor coupled to the end of the drill motor. A TechnoKats design for doing this is in the white sheets, and there may be other designs there.
A downside of using the drill transmissions rather than custom made units is that you need to stop before shifting them or they will be damaged in short order. Our home-made boxes on our '02 robot could be "shifted on the fly" without damage. If you could come up with a way to accurately match revs, maybe the drill transmissions could be shifted while moving. You could also probably win technical awards by doing this.
