Ok, i think i unlocked gregtech based CRCS systems. Rather than try for hybrid balance, split up the plutonium and thorium.
You'll want to use this for the plutonium (can be expanded of course).
Slightly improved. Two more Quad-Plutonium and two more cooling cells. Same micro-cycle time (80s), more EU output, same efficiency, and only one NR per quad cell rather than two. Also filled up the other slots to make transfer easier.
Unfortunately, the cooling cycle for one of the most efficient 4 cell cooling towers is around 640s, that means you would need 8 cooling towers to keep it running.

While the cost to set all that up would be insane, the combined efficiency comes to a whopping 24.
Incidentally, how many cooling towers would you need for all this?
Since we doubled the amount of Plutonium, we can also double the amount of Thorium here. Also, the problem with this setup is there are a LOT of blank spaces here. They will need to be filled up with plates, or you would have trouble transferring the cooling cells. However, if you need a 5:1 ratio, you're going to have to do it like that, because you can only fit four at a time up and down. If you were wanting a Thorium-positive system, you could set it up opposite something like this or a pair of the single-chamber versions.
