Hi, Kael. If you still peeking on this particular thread I have a couple suggestion about the financial backing you could get if you still want to do the game.
1. Choose mod approach like hallmacher have said above. Develop a full mod for civ5 and gain attention, some day Steam or any other digital distribution may knocking at the mod or you could propose to them about option to sell better shape of the mods
2. Choose Minecraft / Beta Test approach. You could develop first and few version at free then become alpha version with option to buy full game at later date with lower price and so on (PS. Don't use ever Paypal for this approach )
3. Just develop the platform mod for any other modder to further enhance it like ffh2 maybe.
Cheers. Waiting for your team big work.
