Um, from what we've seen, I think it's pretty clear that Sadako intended Fi to fall for Lia. The 'revisions' were there to keep people from guessing that was her plan - to make it look like she was playing catch up.
I'm betting she had most of it written before it ever started, and only made minor revisions to respond to specific things Fiona did.
