Not to mention, the armor just on the face of the hammerhead is 7 meters thick. Considering the hammerheads of any warship are the most heavily armored (due to no sidewall or wedge protection, bucklers notwithstanding), the rest of the hammerhead is equivalently armored*. Reduces the available internal volume quite a bit for tubes and such.
*Just checked - yep, 7 meters or more all around the entire hammerhead.
Historically hammerheads had very thick armor compared to broadsides. This juxtaposition in the modern era of Bucklers and end walls, could see a radical change in the degree of delta armor between the hammerhead and broadside. In fact, I would argue that there effectively should not be a large difference. Except very near the impeller nodes. The face of the hammerhead itself? Nah.
That being said, I do not see missile tubes being clustered anytime soon. For starters one does not save much mass. The main reason the ROLAND had them clustered in my opinion is because the beam of the Roland was too small to accommodate normal tubes forcing them into the hammerhead where a smaller form factor was decisive in the design considerations. It wasn't the tonnage that was the problem, it was the form. After all, the Roland was already 190,000 tons; adding another ~1000-10,000 tons would not have seriously impacted the viability of the design.
