You could remove wards altogether but keep sight stone. Or, yes, just increase the cost of wards. My only fear with that is that if wards still exist in their current form supports will still be "forced" to buy them, and the increase in cost will just make the poorer. You could just cap them to 1-3 wards at any given time.
