Just to make you happy the ready use torp magazine is in the hangar, so perhaps you can use some of that space for some reloads.
But honestly I think you're overestimating the number of missiles needed for self defence. If the ship is using its RAM, for kinetic engagements that means many enemy missiles broke through all the other defences (main gun, SM2, ESSM, multiple jamming and decoys).
Not having a reload may reduce your loiter time in a hot area, but at that point you're probably dry on ESSM/SM2 as well and should probably leave.
