This seems unbelievably inefficient. If someone is going to pay for this to be done in this manner, dam you certainly have found the perfect customer. Just a couple thoughts. Have you considered using a CASE IH quadtrac pulling a high floatation pan (they use terragator type tires on the back)? At least use this to haul the material to dump area if you could not use it to load itself? These things practically walk on water. If Your using CAT CTL's do yourself a favor and get some real buckets on them. Those undersized CAT buckets will add more time to this already unbelievable time frame. I think Komatsu builds a large tracked dump truck. They are slow but compared to a CTL maybe not. You have got to take video of these and post it as the job progresses. I would have to see this to believe it.
