According to the old, leaked shooting schedule for TFA that was floating around the internet a few months before it’s release, there did seem to be a planned shot of young Ben with Snoke, in some shape or form. So you’re that probably was intended to be a young Ben.

The shooting schedule also mentioned shots of Leia and Han sending young Ben away with Luke, Ben training with him, and then leaving the Luke’s training temple. I don’t know if these were ever shot, though.

Regarding Hal’s edit, though, I think it is pretty much finished, so I think any big suggestions should be left for general edit threads for this film.
