No, I don't like the idea. It was raised the very first year of this contest and shot down then. This is a buck contest designed in such away to allow everyone to compete on the most even playing fields as possible. It's why you are required to score your first buck because in some places that's all you get a chance at due to the laws of the states.
In the end, you'll find most folks play the game and will pass on a buck that could have made a difference. A small buck turns out to be the average size that wins this contest. By allowing a doe, you lower it even more. My advice to you, shoot that first buck instead of holding out and you will do fine for your team.
Good luck!
