It would be good to have both versions, for sure, so we can see what we like more.
As for the Han vision, perhaps we can do something more ‘real’.
Ben definitely looks behind him, as if there is a figure there. Because Leia no longer appears to him, perhaps we can show Han on the metal wreckage, much like how he appeared in TFA. There’s one shot earlier of Finn and Jannah on the wreckage from that perspective, so we could erase them from the shot, slow it down, and give it some more haze to appear new. Then we can track a ghostly image of Han onto the haze, as if he’s emerging from the mist.
That would be much more in line with a vision from TFA or even ESB, and directly tie into Han’s later appearance on the wreckage.
