Picking your next champion, Request for excel / webdesigner forum members

a long while back riot released this http://na.leagueoflegends.com/en/page/find-your-lunch-table-which-champs-are-friends

which is really nice and i find it awesome..

but there is one thing that i REALLY want to be able to do that i cant do.

which is pick MULTIPLE champs i play and see what picks correspond to all those champs

for example if i use my main it shows me a bunch of similar champs

but i want to be able to select

and see which champs other than those share the most in common with all of them

so since i listed 8 champs i would be able to see

how many have all 8 links in common how many have 7, and so on and so forth

i think maybe having 10 or so select-able champs would be great.

and right now the site HAS the data to do this.. it just doesn't allow you to click multiple champs doing it by hand would take a really long time

and although i would love to code a webpage or an excel sheet to do it for me, idk how to get the raw data from the page. and even then im sure somone else would be able to do it in about 1/10 the time it would take me.

so if anyone has the free time to make either a web site or an google excel doc where i can do this, i would greatly appreciate it.

thanks
