Not really, because of two reasons:
(1) Because I see the PT + OT as the story of Anakin. To me it is a complete story, and as such, until proven otherwise, that's my goal for the PT.
(2) Due to other more important decisions for my edits, the only place "Darth" needs to be explicitly cut is in my Episode III, when Palpatine describes the story of the Sith legend of his master (plageus?, sorry about the spelling), and if recall correctly, I think Yoda says "Darth Sidious" once before he fights him. So there are only two places in my whole PT that actually mention "Darth" other than for Darth Vader. (My Episode I has no mention of Darth Maul since the Sidious plotline is cut, so we never know his name, and in Episode II, there's only once "Darth" mention and that was the Obi-Wan/Dooku scene which I ended up having to cut since I couldn't get it to work satisfactorily the way I wanted it to).
So if I do change my mind, I would only need to make one or two small changes to my episode III. And if I felt it would improve overall continuity, given the small changes it would require, I'd probably do it. But for now, since those movies don't exist, to me it is more important to maintain continuity with the OT, and "Darth" in the OT is just for Vader.
Finally, we all might be compelled to edit the new movies as we were for the PT. ;-)
