Let me tell you one thing -- that I am a Pathan (though Punjab domiciled) and I have seen many Mohajirs settled peacefully in Punjab and KPK. They are naturalized to such an extent that some times it is difficult to recognize them as separate entities. So, I don't think that Biharis (stranded Pakistanis) would pose an existential or any other minor threat to our nation. When I was studying in Lahore, I came across many students who had roots from UP (India), but they were so well versed in Punjabi and other local languages that a third person couldn't appreciate their distinctness. Another reason being the fact that many Punjabi families also have domesticated Urdu.
You cannot solely hold Pakistan responsible for Afghanistan's problems. Afghan resistance started against the Russian backed Marxist rulers and Pakistan intervened after Russian invasion. And Pakistan did its best to accommodate the refugees for the last 30 years. Now I think that Pakistan has had enough.
Then bring them to Lahore and settle them there and make sure that they will never migrate to Sindh. The uncontrolled migration of people from different neighbouring countries to Pakistan has created a dire demographic problem but we unfortunately don't belong to that group of nations who learn anything from history. Be ready to provide jobs, shelter and education to half a million people in a country like Pakistan that cannot provide these facilities to the bulk of its own population. Good luck.
