No, the proposed idea would have had no direct impact on author rewards, because author rewards are a fixed percentage of the marketcap of the coin (so the number of votes cast, for example, has no impact on how much author rewards are paid out over a particular interval of time).

The only potential impact would be if it caused the price of the coin to go up or down. But figuring out whether it would help or hurt the price of the coin itself is quite difficult, because it depends too much on how a change like this impacts human behavior, and you can often only get such answers when you try them out.
