You could put a Curves adjustment layer below your Channel Mixer adj. layer.
If you mess with each channel's curves independent of one another, you can
alter the characteristics of the channels before you mix them. Not sure I
know if there is merit in doing this, but you COULD. ;-)

Antonis, I'm also curious about your custom grayscale curve for display
purposes. This is a custom dot gain setting you create in Color Settings?
And do you set this as your grayscale working space, or apply it as a
profile to your image? Is this in addition to monitor calibration, or in
lieu of it. If your monitor is calibrated, shouldn't your print profiles be
putting your prints in the ball park?
