I don't think there will be a fight between the Greeks and Romans because

1. Jason and Piper love each other very much as you can see from Pipers POV in MoA.

2. The trust and friendship has grown between Frank ,Hazel and Leo in MoA (Although there may be stirrings in HoH).

3. Ofcourse there is a relationship between Hazel and Nico.

4. And dont forget Leo and Jason are best friends.
