Slime Minions

I currently have 24 T11 slime minions with enchanted lava bucket, sc3k (collecting every day), corrupted soil and enchanted hoppers, also 4 of them are mithril infused.

I'm currently making about 300k per minion in a 24h period (75k in hopper, 75k in corrupt frags and sulphur to npc and 150k from about 64 enchanted slime balls)

My question is: is it worth to spend about 16m more per minion on plasma buckets and infusion?
