Any upgrade i've seen done in last few years has been to multi ribbed/ serpentine, it has less parasitic loss than the toothed set up - pretty much only old school roots blowers use them now. They do sound cool though!
You may get some ideas from the serpentine set ups, but at a guess you will still need 3 different belts - try google images
