I don't know about more parallels, but by not including this scene the "family man" side of Michael is barely revealed in GF2. In GF2 we are shown the dark side of Michael's personality. This deleted scene shows the warm, compassionate Michael - the parallel to Vito. You wonder what FCC's reason was for cutting it. To paint a more sinister Michael? time constraints? to NOT have a parallel with Vito? We can only guess.
