Back to ROTJ though going on the idea that his looks are down to physical degradation perhaps the Sith eyes thing could be avoided by giving him cataracts which he wouldn't bother to surgically correct because he can use the Force to see with.
Speaking of eyes it could be possible adding eyes like the illusive man from ME. Maybe to someone that looks important to ROTJ or make him look important..
No cat eyes. 3 Led eyes... it is different :)
