A new kind of combat-focused support, centered on getting kills?

Say a support champion has an execute in their kit and can bind to an ADC: when the support gets a kill, the ADC profits with increased assist gold, and their DPS is buffed until out of combat, setting the support up for another execute. This way the ADC's role stays the same, they're still getting more and more raw power, they don't lose out on potential DPS spikes due to KSing, and the support player feels more powerful and important, being a higher priority target with the satisfaction and freedom of going for kills. It also improves their gold income.

What do you guys think? Also, let me know if this is the wrong forum for this. I thought about posting it in "concepts & creations," but I felt like there's an ongoing discussion about the design of the support role already and this would be the best way to connect the idea to that discussion.
