This one sounds interesting.

But one question:

Why hasn´t a single faneditor cut out C3PO entirely ?

It IS doable.

Same goes for AOTC.

Only problem is the scene with Anakin talking to him after their arrival on Tatooine

and 3PO introducing them to the Lars family.

This could be fixed with a re-dub.

Then he would be just another protocol droid.

Or (hard to do, i know) erase him out of ceratin shots while cutting all the others entirely.

In Episode 3 he enters the saga as Padme´s new & shiny protocol droid.

Would make much more sense for a queen owning a protocol droid than for a single-mom slave.
