Yes, it is very do-able. Much more difficult drive systems are done every day in industry and we can just tap into all that experience and technology right off the shelf.
Hewismayer, I hope you hear back from Gates. If you get nothing from the main company, look up some local suppliers and see if they have any catalog info or other brochures available. You should be able to find everything you need in already published literature and stock catalog items. Small toothed belt drives are used all over the place in industry, this is definitely not rocket science.
Keep us posted, this is a neat project and I would like to see it on the finished model. If you need any more help, let me know. Feel free to PM me if you want to take it off-list.
