No court has that power. The best that can happen are two things:
1) Makes it difficult to impossible to cheat like that (They’ll have to try something else!) in 2022 & 2024,
2) the Biden administration be permanently tarred by this and politically weakened.
I'll add a 3rd. Somewhat a "dream" scenario I saw on FR a month or so ago and expand on it...
The fraud is shown to the public beyond doubt not only in AZ, but in GA as well and perhaps even a few of the other contested states.
3) Trump gets elected to the House in 2022 in a (R) take-over of both House and Senate lead overwhelmingly by MAGA minded people.
Trump is made Speaker and initiates an impeachment against Xiden and the non-natural born Citizen anchor baby "woman of color" Harris.
With the clear evidence of a win by fraud, they are not only impeached in the House but convicted in the Senate and removed from office.
Trump becomes president for the remaining 1 & 1/2 years of Xiden's "presidency." Trump picks Desantis as his VP.
With voting rules tightened at both the state and fed level, fraud is down significantly and Trump beats Abrams in the 2024 election.
Among many other firsts, he goes down in history as the only President to have beaten an impeachment, twice. The only president to have initiated an impeachment while a Speaker of the House. The only president to have served time as president after having assumed the role from the Speakership position.
100 years from now, they build a monument to him along the national mall. It's covered, at least partially, with gold.
