Rough Dreams spilt in two stories?

I have 5 charpter left.
But yesterday i took the plot and i cut what i though it would be useless.
The thing i discovered is that Rough Dreams can be split in two stories. The only thing that can keep the stories togheter is the character of Mrs Granny (never talked about her) and in minor part La Scimmia. But i can easily divide the story in

Srory 1 - Brian, Andreas, Chris, L&L. (protagonist Brian) and it may be titled Rough Dreams, as it talk about how Brian understand that wrestling is not easy.

Story 2 - Olav, Bjørn, Harald and La Scimmia. (protagonist Olav and Bjørn) and the title may be Indre Selv. The title is in norwegian because three of the main character are from Norway and it's meaning is 'Inner Self' as it talks about how Olav and Bjørn finally face their problems.

Now i don't know if i should write two stories about wrestling or i should do like an italian author (they say he is good in his work and i learned many things from him), that is write those two stories and when they are complete combine them in one, keeping all characters.
