What Dan said and two additional things;
You will be better off with two 10m45s in cascode.
You will need 1k ohm gate stop resistors to keep those things from oscillating.

Appreciate if you can draw out how to have two 10m45s in cascode and the additional 1K gate stop resistors.

Basic idea.

I just tried this out with K&K Audio's CCS kit. The kit has exactly the same circuit on what is on your drawing but with different MOSFET.I replaced the cathode resistor of a 'long tail' differential pair of the driving tube with the kit.
It provide quite an improvement. I really like it.
Thanks for sharing the circuit.
