By definition, however, the base story shear is defined for the entire level, not individual bents, irrespective of the load transferring ability of the diaphragm. Considering that the entire concept is screwed up, I would go for the letter of the code.
Anyway, buildings shouldn't penalized for lack of redundancy. Rather highly redundant structures should be rewarded with reduced shears.
