[Death Note, Game of Thrones] Could you kill Jaqen H'ghar with the Death Note if he changed his face in time?

The second rule of the Death Note is that you must picture the persons face in your mind when writing their name (so as not to accidentally kill others with the same name.) Could Jaqen H'ghar change his face before the writer writes his name (picturing his old face while writing) and live? Or change his face after his name was written and live?

A man doesn't have a real name. A man is no one. 

Going by Arya's training, the Faceless Men are supposed to give up their actual identities. Every name they take is an alias.

If you caught one with his alias while wearing that alias' face? Maybe the Deathnote would work. Because it would identify that individual (for a time). But if he swapped faces before Death Note struck, he might dodge death as he "became" a different person. Or it might not work at all, as the intended victim's identity is so fluid.

Good question, though.
