This proposal is an encouragement for players to enter a fray that they are not suited in order to fill the spot. The calculations provided are meaningless because it is not taking into consideration the effect of filling spots with weak players. The stronger guilds will benefit more by scoring many more points than they already do. The struggling weaker guilds will be the losers.
Should this proposal pass the impact would be to lower the quality of brawl battles and for what purpose? - I don't see the merit of this proposal.
