Pretty much impossible without them making her NP give team-wide true invulnerability for the turn instead of normal invulnerability. And with how quickly they seemed to regret giving it to Castoria, I don't see that happening.
But the important thing here is that Jeanne is slowly inching closer to that #2 stalling spot on a stall team. I'd say this didn't really affect her #3 slot role (since if she's in that role, you aren't intending to do burst damage mid-stall), but if she can get an upgrade to her stun skill next then she might overtake Tamamo for the #2 spot.
