Teamate Health bar improvement/suggestion

I thought of something that may improve gameplay experience and wanted to share it. there are times I've been and also seen (spectating) heard other players talk about how they cannot see their teamates health bars during teamfights when there is a crowd of enemies/teamates fighting at once sometimes you cannot see your teams health bars because the other enemies/team are overlapping. this is something that I feel is impacting gameplay in a negative way and could be addressed. Not sure on how it would be improved but if anyone has any ideas or thinks of anything please feel free to share thanks.
