I was just curious as to what might happen if a PF happens after the receiver was down. The defender sort of gives him a little shove but nothing egregious.

A dead ball PF would be penalized independently of the live ball foul. So if there had been a dead ball PF, you would have enforced the IFP penalty including LOD, then enforced the PF against the defense. If that moved the ball past the line to gain, it would be 1/10 for A, otherwise still 4th down.
