Well, since a candidate for President does not "win" until the Congress counts the electoral votes, and since the Florida Legislature was and is the sole provider of electors, I presume that said Republican legislature would have submitted a slate of electors to the Republican House of Representatives which would have satisfied your expectations without violating the Constitution.
The fact that the Florida Supreme Court was planning to create a second, non-Constitutional slate of pseudo-electors is not the business of the Supreme Court-it is the business of the People and their Congress.
