That's still not enough time to conquer all that.
And besides, as I said earlier adding UHVs etc. for a Byzantium civ was require fairly extensive python modding, which means it would be a . .. .. .. .. . to update to the latest patch all the time and you would have to edit the dll which means you need first need to get the uncompiled C++ from Rhye and figure out how to compile it correctly (hard).
So in other words the only way Byzantium is getting in is if Rhye does it officially. And since he has said that isn't happening then I suggest you get over it.
