It would if you just had Kylo remembering Han’s words in TFA. You could potentially have Kylo hear both of their voices, like stream of consciousness.
That would serve TLJ the best anyway, Luke occupying his mind “just like [his] father.”
But, the scene serves a purpose already and we have his vision flashback at the start of the film to illustrate this. If we had it be a ghost conversation rather than a set of memories, that’d be different, but the problem there is that it’s undercut Luke’s existing introduction in the movie later (aside from flashbacks).
