You can definitely pull them off with the exception of Chifu K during online. It usually doesn't confirm the cancel off the H to get the timing easier off of Chifu K which is what I do. The issue with Phase 4 is that most of her stuff needs to be on hit confirm. Such as 66K..but what happens when they block it instead? It's a free punish because you can't cancel the double kick because it's part of the string.
3P etc etc. A strong defensive player can really change the tide of this and take advantage of the situation that she needs hit confirms on most of her warps.
