No online multiplayer? Let me suggest this then:

HEAVY story. One thing that makes Left 4 Dead's lack of story great is the online multiplayer with people. Now it would be cool to have a great story with great online playability, but if the story doesn't really matter and you can't play it online (don't take this offensively) then why would anyone wish to play it? Therefore, I suggest heavy story.

How well would the bots react? What are the improvements from the tier 2 weapons? Why the African islands? What do the new infected add that the other infected do not have? And if more survivors than four are used, then how will you balance the gameplay?

And how will director mode work if the bots get stuck, don't respond, or glitch somewhere so often?

I'm just trying to give you some suggestions and questions to consider for your mod. Personally, I think mods and maps would help the L4D community to stay alive.
