More specifically, it would have no interoperability with the portions of life that target chiral molecules.

Most critically, metabolic pathways.

But that isn't to say there isn't already varied chirality in nature [0]. The primary reason life is generally aligned to one chirality is because its very purpose is to interoperate with the living environment around it.
