Good point, however I still am curious if this is a possibility.
Kinda depends on what an AD support would actually do. Presumably it wouldn't be a traditional support. My guess is such a support would likely be a secondary damage champ, possibly debuffing the enemy team. (like say MF)
Then you have the matter of itemization. Creating an AD GP10 item would likely not fly, as it would be picked up by the ADC, granting them more gold as well. But that in mind, if the AD is melee, they can still benefit from the Relic shield line, MF does pretty well with the Spell thief line, and the coin line is relatively universal.
And again, it's difficult to really create an AD support item, that won't get abused by the ADC or other AD's on the team. The closest thing we have right now his Zeek's, which can grant a whopping 50% crit chances once charged.
