Here is an idea to use both the Helmet scene and the beginning but ALSO use Dominic’s new and improved Kylo vision that leads the reforging of the helmet.

To focus more on Dominc’s vision part, instead of using the helmet scene, what if “we” were to use the deleted scene of Kylo on the bridge form TLJ

This is shown whenever after his meet up with palps. Then que in Kylo’s vision/flash backs with dialogue that Dominic did and then cut to the helmet being reforged.

Could that work?
