Thinking about a barebones improvement to the 436/864u -style sidechain to speed up cap charging. Caps from output amp plates feed  into 6AL5 Rectifier into a power mosfet follower before timing cap network. MOSFET hangs between -B rail and 0V. No voltage gain, just current gain. Should provide more current to charge cap?
 
Or you could go from the caps to the source follower. Then  via two other caps to the diode?
Don't forget  to put protection diodes between the gates and source,
