I now have Kace working/started. It would be a good point to start going between physical and digital models. I could make some good prototypes with cardboard, and possibly the popsicle sticks from a craft store. I should be able to get some models built marble size, later I can scale them down to BB size.

Power
At an abstract level, I think the easiest solution to power is to store up power until there is guaranteed to be enough. This could be storing mechanically in a spring or weight or a pure rolling ball solution where the next clock only starts when there are enough marbles in the reservoir.
One approach for a marble system would be to have a special clock marble. This could be a heavy, large ball bearing where the weight could be used to make things easier. When one clock cycle is done, it must be lifted back up to the top, but the mechanism that lifts it also lifts the other marbles in parallel. This would guarantee to lift some number of marbles before the next cycle.
Tumble Incrementer
I don't have the specific mechanism down. To do a jump, there will be a max jump - say 256. To jump N positions you enter 256-N. Then we increment back up to 256. This is better than a decrement because decrement needs a marble resevoir. With increment, we can put in an increment marble and that will always be sufficient.
A tumble incrementer would have the positions staged around cylinder.
