What if Philia (goddess) was humanity last master?

I’m not sure if FSF anime revealed Philia identity so I’ll just call her the goddess

Philia (goddess) will take Guda role in the story. She’ll have Guda level rayshift compatibility & is a master. Philia (goddess) will be hiding the fact she’s a goddess from Chaldea (somehow it just work)

Her end goal is to save proper human history so that she could enact her plan in FSF. She count as a homunculus, who just happen to have goddess power, otherwise she don’t need a master, or anything.

Can she beat Part 1 & 2 of FGO? Where would she stop if she can’t
