It is not correct, there is clear Hadees that Allah curse those who marries just to make one halal for someone else, so Hanifi also do not condone blatant Halala.
It is clearly required that marriage has be to bona fide, without any prior agreement but after marriege if husband realize hardship of her ex husband and children and decided to divorce her with his free will then not only it is acceptable but Allah would reward him for that.
