Phoebe's Power Development

I've been thinking lately about what changes I would personally make to the show. I know it's self-indulgent but it's also fun so please humor me. I liked the idea of Empathy for Phoebe in S6 but the execution is more than a little messy. The power serves as more of an annoyance for the sisters for a few episodes, is then hand-waved away by a potion, and then is so over-powered in conflicts that it's taken away and never returned.

What if Phoebe's third power had been Astral Projection instead? Hear me out. Fans have long pointed out that Prue and Phoebe's second powers by S3 feel like they should have been swapped, and while I can see it, I do think there's good reason for both of them to develop Astral Projection and Levitation respectively by that point in their lives.

After Prue's death however, I really like the idea of Phoebe developing AP throughout S5. For one thing, it's always felt like a more psychic-inclined power anyway, but also at this point in Phoebe's life, her character arc in this season is largely about becoming too work-obsessed and not having a family-work balance which feels very similar to Prue and how she originally felt the need for two of herself. I also think it would have been a nice way to connect Phoebe to her late sister more by "inheriting" one of her powers so to speak.

This power could have advanced in whatever direction Prue's would have, though I like the idea of Phoebe's version of Astral Projection to be more ghostly like Rex in S1, and then developing to Prue's secondary physical body for ass-kicking purposes.

Sorry for the ramble, but what does everyone think?
