Or a keel box or radially bisected pod open to the hull (sealed inside with a lid) like the old PC-5 or the Nekton series. That would provide a separate compartment for the batteries but do away with the leak problem completely. I don't have the engineering expertise to calculate such a thing, but ABS bought off on those boats, so one must assume that it can be done. PC-5 has a 20" tube section with one small hatch forward to pull batteries through (an enormous pain in the butt, according to the guys who worked on it). The nektons have an aluminum box top, o-ring sealed that screws down to the projecting edges of the steel box keel, which exposes the eight batteries from one end to the other (harder to build but easier to maintain).
What do you think, Carsten? A 1.2m X 30 cm X 30 cm box in the Eurosub? Or a 50 cm OD tube section? Now that KSS has been out to work, do you think it is necessary, or does she have enough power already?

Rootssub?
Make one central Pod under the pressure hull.
If it flood it increase the MG stability
and maybe partly compensate the FSEffect..
