I simply don't see point in changing things right now. When you do make playable tech tree, fire will come out and you will need to redesign everything again, and no one will be able to play with what you have made. Units, wonders, religions will be rebalanced, new stuff added to current techs, so you are simply wasting time, with modding right now. You should wait 10 more days instead.
I personally mooded tech tree for myself, but in way that I altered tech costs (Mounted branch, feudalism were cheaper) and I moved few units, buildings and civics (Prophets and pagan temples came earlier and prophets were much cheaper, so they had use)
