@Meddler: What about an ADC who uses minions/pets to provide firepower?

#ITT: AD Malzahar does not count.
I was doing some Starcraft 2 Co-op mode as Alarak and got an idea on a potential ADC design direction: a slaver/slave-lord who gains power from his minions (i.e. EMPOWER ME, MINIONS!!!!!).
So far there are no marksmen Champions who are able to create pets/minions to fight for them. This feels like it could create some very intriguing gameplay if it were done right, so could this be a direction you might take?
(Before you say "Concepts and Creations", I have not completed a concept yet. I also won't get the feedback I'm looking for in there.)
