As the title says, temporary health items in the healing pool would be a nice addition. Additionally, as far as healing mechanically goes, over-healing health into temporary health should certainly be considered, as no one likes waste.
As far as gameplay goes, I would often see a mountain of healing flasks and pay them little mind, whether having my own source of healing or simply not needing any at the time.
Temporary Health items would enable players to consume those idle items as they pass by for additional protection in for additional temporary health that would deplete over time (or when damaged of course).
Thematically, they could be a bottle of snake oil or something along the lines. Either way, the presence of temporary health/overhealing could be a great addition to Far Far West.

#Temporary Health or Over-Healing

My only problem with this is that you technically don't even need healing bottles in the game. Ya know, the main item for healing you can simply not use and regain health still. There's literally a good couple of options for healing.
Secondary you can put healing on hit, weapon tweaks that can do healing, health on kill tweak for player, voodoo joker that steals hp from enemy, have someone else heal you with voodoo joker, utility item that heals.
Also not healing but voodoo joker that makes you invincible. Technically works like an infinite shield/overheal.
I love the idea, just doesn't feel like it would be necessary in this game.
excellent points, and I suppose I should have elaborated on my theory for over-healing to benefit those other systems as well but as far as giving more heals or offshoots of them would offer build variety in some niche cases
