The Use of Souls in Enchanting Environmentals

In Minecraft Dungeons you collect 'souls' to enchant and upgrade weapons and for other means
so what if Minecraft added souls?
There would be a separate bar (like the experience bar) that you can gather souls in to enchant weapons with more MAGICAL enchantments. For example, there is fire acpect, which is an environmental enchantment that doesn't affect the weapon itself but rather affects the entity you hit. That would require souls maybe 1-2 souls to enchant it. Souls would be used for more environmental enchantments like frost walker, fire aspect or riptide. 
Souls would be collected by killing hostile [living] mobs like creepers, pillagers, endermen, piglins, hoglins etc, and other mobs like the piglin brute and maybe hoglins will give you 2-3 souls because they are tougher mobs. Mobs like the Ender Dragon and the Wither will give you 5-10 souls.
This idea will change the way enchantments are used and make for more interesting gameplay.
Also, with the implementation of souls could possibly come with more magical enchantments
that affect more of the surrounding area or entities.
This is just an idea.
