Concept - Champion & Item Builder/Database

Hey guys,

There are loads of online item databases and even item/set builders, but what they all seem to lack is what your full stats would be and be able to change and swap out gear in real-time to figure out what gives me the most bang for the buck. I'm getting ready to start building an excel spreadsheet (eventually online configurator) that lets you choose your champion, choose the level, have it load up the champions base stats at that level and from there you could choose from every item in the game and have it update your stats in real time. Eventually, I would like to build an actual calculator that once you choose your champ, and choose what stats you want to prioritize, it will auto sort and recommend items/builds that will maximize the stats you are focusing on. (including gold efficiency)

What do you think? Is this something you all would use? Any recommendations?

Any info and help is appreciated. Thanks!
