The first alts are Garcia/Mladenovic who will surely get a wild card so everyone can move up one slot already, and there's another French pair before Alicia & Olivia.
Before the draw happens if one player drops out the other person can repair with someone else, so don't expect too much movement upwards before then.
Tara & Emina are almost certain to get in.
Sam & Heather hopefully have a chance.
Alicia & Olivia I would put on the unlikely side, although you never know.
