Will sns2 have 2 storylines?

If sns2 gehna story is inspired from another show then how modi family story gonna mixed with it...and it is not believable that modi family is only cameo...much has been in hiding- ahem memory back, jaggi- ahem face off, and a lot more.. So they are not leaving anytime soon...and I think makers have seen that in many previous show new season, if old cast is not there, 99% it will not get trp.. so here they can use modi family story in focus incase new story didn't work
