You can make a bioactive enclosure, but that is unrelated to any feeding regime. Are you asking if the isopods and springtails will survive off that poop? They could, but I prefer to spot clean, so there's not poop laying around. They don't need the poop to survive. They can eat dying plant matter, such as if a leaf falls off a plant or if you put leaf litter in the substrate. Among other things within a bioactive enclosure.
