Hilltop, the Mobile Dimension Saw uses v-belts with quarter twist to run the edger blades. The main blade runs off of 6 belts directly from the engine, and the main blade's shaft doubles as a jack shaft to run the edgers via another 6 belts. This system works extremely well, so you might want to borrow some ideas from it.
I'm fairly familiar with both the Lucas and Peterson mills, and have been wondering about something. In order to double cut with the Peterson, you have to take the blade guard off. The guard on the Lucas can't be removed, so you cannot double cut without turning the saw head around. What I wonder is, why not make the guard movable, so you could just swing it to the other side for double cutting?
