Yeah, I think it would be hard to really show enough that would be a satisfying answer to that question, I just thought it could be the initial motivation for why Kylo connects with Vader’s helmet.

I had totally forgot about that scene between them. That definitely would need to be changed, but like you said, if you can change it appropriately it could help show the two villains at odds. I think another scene I would like to change somewhat is the First Order meeting.
These scene goes like this:

First Order Officer Quinn speaks up, dismissing the Sith Eternal as “a cult, conjurers and soothsayers.” Pryde refutes these concerns, stating that the resources of the First Order will be increased ten thousand fold by the incorporation of the Sith fleet into their own ranks. With a spiteful glance at a glowering Hux, Pryde notes that the influence of this ancient power will “correct the error of Starkiller Base.” Unconvinced, Quinn wonders aloud if the ships are truly a gift, and what Palpatine might demand in return. In response, Ren brutally chokes the general through the Force and lifts his body to the ceiling. The fallen Jedi then commands his officers to prepare to crush any worlds that will defy the Order, and that he and his acolytes will be hunting the scavenger.

Why Kylo chokes that guy makes so little sense to me. If anything, he probably agrees with Quinn more than anyone else in that room. He’s probably bringing up points that Kylo has already thought about. Like you said, I’ll have to go back and watch it again, but I would really like to be able to end this scene without Kylo choking that officer.
