Obi Wan Having two apprentices doesn't really work.

1 being it was NEVER mentioned in the OT.

2 it would WAY too confusing in the OT if that were the case.

3 being IMPOSSIBLE to pull off, with out some really good CGI or EXACT look a likes of Ewan Mcgregor and Hayden Christensen if not them. It would just be better to re make the PT which I nor I assume anyone else including J.J. Abrams is going to do.

Its plain and simple. Anakin and ONLY Anakin is Obi Wan's apprentice. I may not be able to keep Darth Vader's identity a secret but I can hopefully bring the PT In line with the OT.
