The basic issue is that TFA and TLJ’s characters are not the same characters. It’s very clear the respective directors wrote their own versions and they are very hard to reconcile. This doesn’t mean any one is particularly better–just that they are different and uneven.

A smooth edit would have to reconcile the characters in either direction–either change TFA or TLJ’s portrayals.

Let’s be honest, Snoke was pretty much wasted. The rich playboy appearance would be fine if it wasn’t erased in 4 minutes after introduction, so that image was also useless. I’ve said this before; there was a huge missed opportunity with Solo to fix the majority of Snoke’s issues–instead of Maul, make him Q’ira’s boss. One cameo explains what Snoke was doing in the OT, how he got power, and fits his rich crimelord image.

As it stands with the current story, the smoothest edit would reconcile the fact he’s a clone/experiment of Palpatine. Especially as Mandolorian seems to be heading in that direction with Gideon’s experiments.
