After seeing your photos I would say definitely revise the design. Make the frame lower so 4-6" of the differential sticks into your drum and mount the blade directly on the yoke with bolts. That will make a strong design, and you can seal it with bondo or mastic between your tank and the differential. It is not easy but doable to cut the hole in your plywood and drum bottom to closely follow the contour of the differential. The photo in my previous post is a link to my mixer photos which do not show the plywood I added later. I'll eventually revise that page, when I get some more round tuits.
I would be cautious moving what you have. It looks like the shaft is not centered or square with the differential, and the only support in the middle appears to be a hole through plywood and the metal bottom of the tank. If the shaft is off center than it will vibrate a lot. There is not much clearance between the blade tips and the drum sides, so any flopping around would probably result in a short drum or worse.
The biggest problem with this type of mixer is that the seal on the differential will leak and let water into the gears, and a little oil into the papercrete mix. This was never an issue for me, or for others with the same type of mixer. The water in the oil doesn't seem to hurt much, and what oil gets into the pc just vanishes as you use it. Shop around for an old truck inner tube and make yourself an elephant trunk on the bottom of your tank. Buckets get old really fast.
