Could we slightly increase the lifesteal on machete and it's upgrades?

Disclaimer: I am talking about monster lifesteal only. None of these items have real lifesteal and I don't want real lifesteal. 8% lifesteal may seem like a lot, but many of the champions with little or no sustain deal magic, on-hit, or skill based damage that does not utilize lifesteal at all.

Tanks are dominating JG right now, and that's fine. I don't really feel like any of them are unbalanced besides Hecarim. What bothers me is that AD champions are at the very bottom of the JG winrates since the removal of devourer especially. None of the top 10 JG champions really care about lifesteal besides wukong. Yi, Udyr, Trundle, J4 and more are suffering.

I think increasing the machete lifesteal from 8% to 10%, and the upgraded jungle item from 10% to 12-15% would be a very tiny buff that would push all of the poor performance AD junglers slightly closer to viability. Maybe even give 15% lifesteal only to a full upgraded jungle item, or even only warrior. That would also make warrior slightly more appealing in a meta where nearly every AD jungler is skipping an upgraded jg item and buying tiamat and ghostblade.

This change would allow AD junglers to come out of the jungle just a tiny bit healthier and boost nearly all of the low performance junglers while not phasing the higher performance junglers and not requiring nerfs.
