Yes, that is permissible.
Shaykh Saalih al-Fawzaan said:
If you have a half-sister from your father, then it is permissible for you to marry her half-sister from her mother, because there is no relationship between you and her half-sister from her mother that would prevent that. Allaah says (interpretation of the meaning):
Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) narrated that the Muslims were unanimously agreed that this kind of marriage is permissible. He said: It is permissible for a man’s half-sister from his mother to marry his half-brother from his father. This is unanimously agreed upon among the Muslims and there is no dispute concerning that. And Allaah knows best.
