The following changes:
1. Chirurgeon can use alchemist's tools instead of healer's tools for medicine
2. Expanded formula list for research field to any elixir that does not have the poly/morph traits
3. Limit application of elixir of life to only once per round
4. Change Quick Bomber to something more generic and allow elixirs of life to be drawn in the same action as whatever you do next with it
5. Change Healing Bomb to use one elixir of life and one reagent, but also have splash healing equal to the number of healing die
6. Change Combine Elixir to allow one elixir of life and one reagent to create a double strength elixir of life
4-6 can create the following combinations:
1. Single action application of elixir of life to self or adjacent allies
2. Two action ranged elixir of life (healing bomb) with splash as the incentivizer
3. Two action double strength elixirs of life (one action to create, one to administer to self/adjacent allies)
4. Three action double strength ranged elixir of life (one to make double strength, one to make bomb, one to throw). This would require two reagents, one for each change.
Outside of combat, I would keep Paizo's 10 minute limitation to Perpetual Infusion elixirs of life.
Is this too much? How can I fix it while still making chirurgeon an attractive option for healing?
