Ultimately, you'd be better putting a pair of the 2nd and 3rd stages to load the first stage plate. The capacitance is huge by pre-amp standards, and it would allow at least an order of magnitude drop in output Z. The transistor ought to be delivering more gm than a tube, and so drop its output Z into a few tens of Ohms...I am not going to go to that level of complexity in a linestage when I can just reverse the plate connections in the amplifier and re-invert there...assuming I'd pay this any attention in the first place( beyond making sure both amps delivered the same phase).
When multi-amping with an active X-O, the final polarity stuff gets done at the speaker terminals anyway.
cheers,
