It honestly is not worth doing at this point. There are so many faucets and faucet rotaters already... and most people have seen that it's not a good way to spend time.
I think there is an opportunity for better faucets to exist, since so many have become copies of the same spam ad heavy interface and huge payment promises with low payment reality.
Faucets have a bad reputation, but they do serve a good purpose in the bitcoin economy. Why not build one that doesn't replicate everything people hate about faucets?
Have a more interesting user interface. Have payment and collection structures that make sense. Follow through on big payouts and share the face that a real person has collected those big payments! Fight the bots that exploit the system.
I can't offer details on coding and whatnot but hopefully my thoughts here have been constructive for your approach. Let us know when you have it set up so we can beta test for you!
