Am trying to find something analogous to the above definition, would anyone know if something like it is in mathlib? I'm trying to see maybe if I can arrive to it through some variation of Action maybe

If we ignore the enriched aspect, it seems like a monoidal functor from M to the category of endofunctors of C (which is monoidal for the composition of functors).

Thanks! I've been tinkering around with variations on that idea, it seems to me we might not be able to lift the concept up to enriched categories without the notion of C-module categories as in https://ncatlab.org/nlab/show/action+of+a+monoidal+category

seems like we would need enrichment is preserved for category of endofunctors otherwise, which seems to only be true for enriched ordinary categories
edit: might have been mistaken, working on a proper encoding
