GZG:(FB) ADFC question

In designing a cruiser along the lines of an Aegis class,
(armed with SML's and PDF"s) I had a question about
multiple ADFC's.  If a cruiser has 2 ADFC's can it cover
two adjacent ships?  If so would this give rise to dedicated
Aegis type ships armed with six or seven PDAF's and a
couple or three ADFC's?
