Also, take a look at some of the Gozzard designs. They tend to have unusual galley and salon arrangements along the lines of what you are describing. Another one is the new Island Packet SP cruiser. One other boat I'm familiar with that has an arrangement which sounds similar to Sasha's is the New York 36, built by W.D. Schock.
But I'm not sure it could be done too well in a Catalina 27 (is that your boat or am I pulling that out of thin air?).
