I'm way too lazy to double check the math, but it looks on the face of it like the 6N6P is one answer to the numerical problems you've posed so far.
As for sound, I would prefer the best 6SN7s. But who can find them and who can afford them, once they're found?
Also, to be fair, I have never played with 6N6P operating points. It may well be that it can be tweaked and optimized in a given circuit, just like the tubes I have played with in order to get the most out of them. The 6DJ8 is an example of a "lowly" tube that changes sound character dramatically according not only to operating points but it also gets down to the particular resistors used to load it. Maybe the 6N6P is similar?
Another feature is that you can strap the plates or run parallel, for more gain or still lower impedance.
