By my math you have brute forced about 35 million keys (35e6) of 5.4e12
keys (5.4 TeraKeys). At only 2 MegaKeys an hour it is going to take you
a while to finish. There is a reason why aircrack-ng doesn't have a
brute force mode for WPA cracking.

I don't believe so. IIRC nice doesn't adjust the relative cpu time a
process is given. Setup properly you mkList script should block (wait)
for the fifo/pipe to have space when writing.
In this case you don't need a fifo/pipe. just this:
mkList | aircrack-ng -w -

Then use the wordlists in /usr/share/dict.

It is far easier to have the script generate valid keys then to try and
filter out bad ones. Generating key or password guesses efficiently is
actually a harder problem.
