FWIW, it sounds like the judge may be open to ruling against such an action. From his decision at https://aboutblaw.com/blQg:
> Even if Plaintiff had made a “vote dilution” or “one person/one vote” claim under the Equal Protection Clause, it fails. Plaintiff does not assert facts that would adequately support such a claim. Plaintiff does not allege... that natural person voters are a minority or are politically cohesive [or] that entity property owners vote sufficiently as a bloc to usually defeat the preferred candidates of natural persons.
Although he also notes that the recent Callais case, severely weakening section 2 of the Voting Rights Act, may change this - and, of course, waiting until the Legalize Asbestos Consortium is doing its thing and trying to file a lawsuit is much more complex than preemptively saying "only natural persons can vote."
