An idea for less snowballing matches, good or not?

Riot should make it where a player does not get bounty money off of a player who is on the negative. For example, Teemo goes 0-6 but finally gets their flow and gets a 3 kill streak. If a person who is 10-0 would kill said Teemo, they would not receive a bounty off of the Teemo. Obviously the Teemo would lose their streak. There can be some tweaks to this of course. Having a bad start shouldn't determine your whole match. This could help keep the 10-0 guy from having easy bounty kills and making the match less snow bally.
