I have not had any issues mixing them, I have a smaller tank of around 50L, and the cherry population keeps growing.
I would guess and say that if the cherries have somewhere to hide, you shouldnt have any issues.
Ghost shrimp will harrass the Cherry shrimp... if they can find them. As long as you have plenty of hiding spots for the cherries, they should be fine. Or, get a lot of Red Cherries; safety in numbers
