When a candidate signs the certification for his/her Electoral College delegates, that is an official act which has a factual consequence. As a result, the appropriate number of Electors will become official candidates on the ballot in each jurisdiction. (Under state laws, when you vote for “Smith” for President, you are actually voting for the Electors for Smith for President.)
So, contrary to your conclusion, the issue is ripe for adjudication. The case does NOT have to wait until a candidate wins the election before a decision can be reached.
As for your reference to Bush v. Gore, I wrote one of the 14 briefs in that case. There are no issues common to that case and the present issue.

***But... can we time it so that it gets decided in October? ;-)
