Lifeline Perks Change

Had a thought and wanted to get some opinions. For a while now Lifelines perks have been relatively weak. She isnt in the upper tier anymore for support picks many times. What if there was a perk, purple specifically, that while drone was active on a teammate or self that if you were knocked it would start an autorevive? Depending on the remaining life of drone would depend on a full or partial revive as well. This could bring her back to upper tier and be a fun mechanic.

Just a thought. Maybe someone could refine some mechanic like this better. Hers and cobduits perks are just awful right now.
