I was thinking about widening the carriage for the suspension and putting a dual sprocket with a bearing on the dead axle that is the pivot point. Then run chain to the omni.

The point of using omnis is to avoid needing to "rock." I don't get how it would be smoother to have it rock AND have omnis.

And if you want it to rock, why don't you just drop the center and forget about the suspension?

If you want to still have the suspension, you could either do what you suggested or make the suspension go up and down along an arc with radius equal to the distance between the front and middle wheels, so the chain has a constant distance.
