User blog comment:Wil Skywalker/Do Luke and Leia ever meet Padme as a ghost?/@comment-26275684-20160220185332

Even though this blog is old I might as well answer this since no real question was ever given.

Padme couldn't use the force so it would be impossible for her to become a force ghost.

Even if she was, returning from the dead was a complicated process only a few (are known) to have achieved: Yoda, Obi-Wan, and Anakin.

Even then, it's heavily implied the ability to become a force spirit wasn't known. For Yoda and Obi-Wan (and possibly Anakin) to learn, Qui-Gon had to contact them from the dead and teach them how.
