It really does sound like he used ANH as a template. I hope it has more emotional impact than Old Ben's death. Do Kylo and Han know their relationship with each other?
According to the MSW version of the call sheets, Han has an emotional breakdown on the Falcon en route to Starkiller Base after Maz shows the group a flashback vision of Kylo murdering the Jedi and Finn consoles him. After they crash the Falcon in the snow and head off to the base, Kylo finds it and "has a moment" on Falcon. There's also the rumored "You're not my father!" when he slays Han.
