This may be extra-difficult, but what about digitally-editing a establishing shot to include Vader’s castle in the far background? This could make the planet a bit more recognizable for those who watched Rogue One. Or perhaps reusing the lava/smoke shot from RO, with some color correction and the shuttle replaced by TIEs/troop landing craft, to extend the intended establishing sequence following the First Order from atmosphere to surface (much like TFA). Though, since I like the game shots, maybe my suggestions are biased towards featuring them as part of this sequence.

Hal, in the event you cut the video game footage altogether, at least keep the TIEs flying shot. Every added second is worth it.
