We're more in number than Baloch or the Azad Kashmiris. 8-10% of Pakistani population.Muhajirs make up a small minority of Pakistan. It's like saying the White Western European English have racial connections to Africa because there are a significant numbers of blacks living in the UK. In reality both have no connections to one another.
I don't want Pakistan to change its policies or do anything for Indian Muslims. It shouldn't. It would create more problems for them actually.
