The fleet has fought very long engagements though. We expended thousands of missiles taking El Dorado, including multiple rounds of special purpose missiles. Using reduced size, rather than boxes, for non-hangar ships gives us the ability to reload if necessary, or even to pull off tricks like following up a slow round with a fast to have them synchronise arrival.
We could theoretically do what you suggest anyway, but multi purpose ships aren't always great at any one thing. Bombardment in particular requires massively long ranged FCs.
