I don't think that would make any difference at all. Obi Wan's robes were left on the Death Star, and likely was destroyed in the explosion. So by this logic, should Obi Wan not have access to his robes as a ghost?
This is sounding sillier and sillier to me suddenly... the whole debate on what a ghost gets to wear or not wear I mean! Or how old they appear, or how much hair they have... it gets to be a bit much.
But I have a question anyway: If Qui Gon is the original Jedi Force Ghost (OG: Original Ghost!), and thus taught Yoda and Obi Wan how to also become force ghosts, then why is Vader able to do the same, since he never learned this technique?
Related question: Why isn't Qui Gon not there with Anakin/Yoda/Obi Wan? Yeah, he doesn't know Luke, and Luke would only be confused if he saw a strange Jedi standing there, but he is still the only other Jedi (non-EU) to be able to do this.
Reminds me of this old mock up that has been on youtube for quite some time:

(I did not make it)
Looking at this mock up, it wouldn't be too much of a stretch, since in the edit, Luke looks away before Qui Gon appears... perhaps it could be interpreted that he appeared to observe what he so strongly believed in: Seeing Anakin's success in balancing the force.
Ah, early morning ramblings... I get carried away, sorry folks!
