Companionway steps on the wall of the head? Nice outside the box thinking. So, no more removable steps? Which way is the head going to be oriented? Excepting the steps on the WC wall, maybe a curtain could be used there as well? Might not be a bad thing to be able to vent out the companionway...
While you're redoing things, maybe you could move the companionway entry off center to make more room for the head? That's semi tongue-in-cheek, but it would make more room... I love following the progress of you guys who actually get things done on your boats.
