I have a similar situation
Kenny,I will be interested to sse how this project works out. I have a 1982 H30, and I have been planning a similar project for my port cockpit locker, which is above the quarter-berth. My quarter-berth is never used for sleeping, and therefore has become the catch-all for whatever will not fit elsewhere in the cabin. My thought was to cut out the bottom of the locker, put in a false bottom, and put shelves, or other storage area in the quarter-berth. The false bottom would make this area accessible from the cockpit. My only concern would be that cutting a hole in the bottom of the locker may or may not compromise the structural integrity of the cockpit. I don't think so, but I could be wrong. The starboard cockpit locker is open to the engine compartment and the lazarette.I'll keep watching to see what advice you get.
