Definitely against this idea... Also I think you misunderstand the whole lore point, I don't believe it takes away life force rather that by overusing anima it could have potential damage. Eventually one might disappear into the aether forever, or they cannot reconstruct their bodies. Might even have a point where overdoing it cause damage like a missing limb, deformities, etc. While the whole idea could be interesting for a "lore" approach it's just going to cause more trouble than benefits. Leave it as is.
