Perhaps I'm being mean?

A saga edit with Sitheyes and even Jedeyes could possibly work but they would have to be applied consistently.

If Maul and Palpatine's eye's work the same way as Anakin's would they be switched on all the time like in TPM and ROTJ?

They would have to be switched on and off, or ALL good Jedi would have Dune eyes and all Sith would have fiery eyes all the time. Maybe Maul had impure thoughts at all times?

Wouldn't Anakin's be on through out most of his ROTS battle with Obi-Wan?

At the very least from the moment he chokes his wife.

Would we see them fade away when Luke takes off Vader's helmet?

If it was an immediate effect, it would have faded well before then.

I'm not saying we should do this, I think its silly. I'm just breaking it down for those who want to do it, heaven help them.
