I think there would be Sandhir...
I mean both would be there for each other but at the same time not bound by a relationship...Like Randhir said "Hum sath hai par alag hai".I think neither Randhir nor Sanyukta would get married throughout their lives and it would continue in the same manner...Likewise trying to prove the same thing that career oriented women can't handle relationships...Or the guy changes from being a patriarchal to being a feminist which transformation is currently taking place...If you would have noticed then Randhir's character has been transforming continuously...So if Sandhir has to patch up then Randhir has to become a feminist supporting Sanyukta's independence unlike last time in their relationship when they fought mostly due to the fact that Sanyukta was independent and Randhir wanted to make her dependent and which resulted in their break up...So now is the phase of Randhir's transformation and if at all it is complete then we may find Sandhir together...
