@Darth Sanguis - I understand where you're coming from, but the problem with it is if you expand the game so fleets can fit in your formula (Large, Med, Small, Flotilla, plus fighters) then inevitably that means some people will use those extra points to take even more small ships, or squadrons, or whatever......which would lead to your "Diverse" fleet getting outactivated, out-squadroned, etc. Same problem still applies.
The only way to avoid what you're suggesting (without completely restructuring the game) is to mandate that fleets include a minimum number of ships from each size class....which would pretty much kill fleet diversity. Something akin to 40k's "Core Force Org" chart. And anyone who's played 40k knows all about the issues a Force Org chart has....more flamewars about this topic have occurred than Armada players could possibly imagine . You don't want to get into "Force Comp" arguments. That's one of the things I love about Armada...
