Of course, Charles Evans Hughes stepped down from the Court to run for president, so it's not a certainty it would stop him, but if William Howard Taft accepted a Supreme Court nomination; say TR figures Taft would rule in his favor and that would help more than anything? Who would accept Teddy Roosevelt's "anointing" as his successor? Or, might TR decide to stay on and run in 1908 without Taft to run?
