That could be an okay stop-gap solution if consensus couldn't be reached on new laws, since conflicts between states have original jurisdiction with the Supreme Court.
A concept that I heard about in at least one other country is that Governors and Presidents have an additional option when the legislature passes a bill to their desk. Instead of "sign" or "veto", there is at least an additional option of punting it directly to the constitutional court.
(Another tweak is that the constitutional court is not simultaneously an appellate court.)
and then of course is what I observed about who can have standing to bring something to the courts at all. I think one shouldn't need to be harmed already to bring a case to review.
