I know that many players will say "ap supports are better" but a little item or a champion would be really nice. If you are reading that and you are from Riot Games would you consider making an ad support? I hope you'll notice my post, and if you did thank you! Forgive me for my grammar ^^
I don't see any good reason why this can't happen at some point.
Maybe that Noxian Drill Sergeant idea certain people have been asking for?
Then again I did have that one fire monk idea I suppose could scale a bit off AD rather than just full AP...
it would be hard.... you need to diff types of damage in the bot lane otherwise the sup and/or adc could just stack armor.... hell it takes only a 
to make 
a bitch to deal with
At least you aren't asking for a Suport/Marksmen
Considering that many AD champions are melee and AA reliant, it's hard to create a support and / or item that can't be abused in solo lanes, but still work fine as supports. I guess you don't accept Tank supports like 
?
