Nah, that's not Simon. There's no yellow and notice the shapes of the colors, lack of center panel. It's not one of the newer versions either.
I'm positive it's supposed to be one of these guys from 1953 WotW:

The RGB thing is also perfect for a projector.
...what I'm NOT sure about is what the thing under the "face" is supposed to be. Not sure if that's some form of the martians I don't remember, if it's some other reference, just random, stylized version of their bodies, etc.
On the BB8/R2 - I first thought it was an R2, and I agree it's not a perfect match for BB8 (missing some greebles, paint, is way too big). But it doesn't match any variety of R2 unit either (even less than it matches BB-8's head), and I feel like they wouldn't add a SECOND R2 unit (and the one on the right absolutely is). You might be right, and I'm not convinced it's BB8, but I'm going to say I think it's really unlikely to be an R2. Now I'm betting it's something else entirely.
