if you think of universe as minecraft lattice (which is arguably best way to think of it and explain all of physics currently in existence in intuitive level) then yea, it can be like eg a spin lattice discrete at some plank length from which field perturbations as particles emerge..look up spin lattice from https://arxiv.org/abs/hep-th/0507118 so basically bringing back idea of quantum ether cuz explaining empty space with waves without some underlying structure doesn't really make sense anyway since all other waves have mediums in nature.
