dunno about C3C, but in the vanilla version I was able to do this. I knew this trick is possible, because I had read something about in the "zero science rate" topic in the War Academy and made my own strategy.
Most of the technologies I was researching, got researched by other civs before me, but I was able to get one or two (which is better than none) and sell and/ or trade them for other technologies.
I did this until the discovery of economics because I had already rush-built a lot of libraries, marketplaces and banks and had just completed smiths trading co. which gave my economy an extra boost...
