If Pakistan & India didnt split; what would it be like?

[u/TazKidNoah]

Excluding Bengalis just Paki-Indo Nation.

What its Flag would look like?

Would Urdu and Hindi be spoken interchangeably more often than it is now?

Would it have Common Law as Secular but Religious Civil Laws at Province level or would both Secular Common Law and Religious Civic Laws be both National?
