Since we're playing casting agent, I think you have to give Ralph Fiennes a solid look. Check out some pics via Google, especially recent ones where he's sporting close-cropped, balding hair. Note the nose, eye/brow area, chin/jawline, etc.
With the right stubble, glasses, etc., it could work.
And I hate to say it (because I'm not a fan of the guy), but look at Bradley Cooper. Again, focus solely on the prominent facial features/shapes (nose, eyes, jaw/chin, mouth, etc.). A bit of hair and makeup work could probably get him pretty close to the look because, facially, he's quite close in some key areas.
The idea is to get someone close enough in those key areas (jaw/chin, mouth, nose) so that you don't have to use a bunch of fake-looking, obvious prosthetics.
