In the art-of book for TFA there is actually art depicting this. It's an idea they toyed with earlier on that could still be reused in the future.
Anakin's ghost was constantly shifting between the light and the dark. At one moment looking like Anakin (PT Anakin rather than Sebastian Anakin) before what looked like metal and wire crept across his face and suddenly taking on the visage of Vader. He exists as both simultaneously.
Real neat idea and I'm for it.
Ehhhhhhhhhhhh that kind of torpedoes the entire arc of the franchise. His spirit was redeemed. Tortured Force Ghost Anakin is unnecessary.
