I like your spiritWell i did say anyone, so that includes, Bengalis, Afghans, Rohingyas, Tajiks etc etc. As long as they take the pledge to be loyal to Pakistan then grant them and their kids citizenship.
Now i know many people are going to go bonkers on this, but my reasons are simple. They are already here and have been here for so many decades, there is only a slim chance of them going back, so might as well grant them citizenship and bring them under the tax umbrella.
