She is the type to change her mind and is creative but I can't see her joining Phase.It's hard to say with her. Officially Beatani sounded like she was kind of done with vtubing and wanted to focus on her at the time new job and real life stuff. She also stated she preferred the old vtubing methods of short form videos over livestreams.
Having said that, she is 100% the sort of person to change her mind on a whim and or menhera thought process and she is someone who enjoys making stuff. Additionally she was known by fishman to an extent he thought of her positively when she just gave half of the pippa collab stream money to her unprompted and she 100% fits into the hiring agenda of 'sad girls but hot'
I have not seen anything that would indicate it's her but it's not outside the realm of possibility.
She would rather be some JP 2 view messing around with VR chat on mute.
Beryl would be a fun get but she might have moved on as well.
No way Chinchilla joined.
Temako would be an interesting get but I highly doubt it.
In reality, I think it's 5 people none of us know. That's also kind of fun. Nasa's collabs with Nopi are cool and there are lots of JP indies to collab with. Personally, it would be cool to see Coyo collab with a Phase member. Hoping for at least one hag to glue the bunch together.
