Give Supports a special "support" minion to kill

Im not sure how effective it might be if at all, but i think since supports can only look in hunger as their adc's take all the cs, kills exp etc Why not make a special "support" minion that would function as a normal minion BUT wouldn't give gold or exp to anyone BUT the support.
Maybe it could be green in color and have a nurse cap on its head and would give to the person that picked the supp role some gold and exp its just one minion but what do you guys think? It could come in lane with all the minions bot like every 2 mins.
