Does anyone know who this is in Rogue One’s 2nd trailer (with their back facing the camera, at 1:20)?

My thought is that it’s Guy Henry as Tarkin, sans CGI, but I’ve never seen anyone mention it before, so maybe I’m way off base. I don’t know which other character/actor would be in the scene, shot like this, with that uniform.

One of the things they claim in the behind the scenes for the (extraordinarily tasteless) CGI Peter Cushing is that they never had any backup plan if it didn’t turn out, and all the released set photos show him with the full dot and camera rig for his face.

If this is Guy Henry, he looks like he’s in full costume and makeup but with his natural hair and no augmentations, which could mean that they potentially shot alternatives as a safety (or if saner voices had prevailed and made them reconsider). Is there another character in the room that fits the bill or is a glimpse at yet another option they had on the table for that film?
