Dangit Kurt! Now you've got me daydreaming instead of working again! I was going to comment on "cutting" your large deadlight in half with a bulkhead and the potential maintenance issues should you ever have to remove said deadlight - then you posted the second drawing. So I won't point that out, although I guess I just did.

So, in thinking of your aft head location, I got to thinking of a couple of other layouts with the same, like the Flicka and the closely related Allegra 24. (I just added a pic of its enclosed head) Same beam, BTW. Both have nice and open v-berths and an enclosed head.

So I say, how about bring that bulkhead forward to between the deadlights? It takes up more space, but any "extra" could certainly be used for wet storage, like up under the cockpit. The extra bit of room just may make the head a little more welcoming and a place you could sit and read a good book, or, heaven forbid, get rid of some bad fish... Just a thought.
