I don’t like the cloning idea because it just raises an inevitable question at the end of TROS: is he really dead? Surely he must have a plan Z - another load of clone bodies somewhere! Bleh. I know canonically his decrepit form in TROS is because the cloning was imperfect or whatever, but when I first saw the movie I just presumed he looked like a corpse because he literally was a corpse being Darth Sion’d back to “life”. The Frankenstein imagery of the big claw also compounded this. Luckily, TROS is a great movie for headcanon since most of the plot around Palpatine is exclusive to the novelisation, so I can continue to gleefully ignore whatever I don’t like until Filoni or Soule or someone redeems it.
