I agree BC and IC2 are both overused, but they do add some great things. A lot of the mods you have on your client would be great additions to this modpack, on my client I have:
Computercraft, All of the flans mod addons, including manus, OpenComputers, Orespawns, Portalgun, Mo Creatures, Open Peripherals (another mod they should add), thaumcraft, and ars magica 2
