I'm glad you like it but it would be a real bugger to pull off adding so many elements and selective colour alteration convincingly.

Still maybe someone could do it.

I'm not sure if Palpatine really cares though.

He is the Emperor of all he surveys but he walks around in a potato sack.

If he still wore the sort of grand robes we saw in ROTS a bling throne room might make sense but I think he's actually above those things by ROTJ.

He's like a distorted reflection of Yoda.

Now that he controls everything he doesn't have to impress anyone (the art and fine furnishings were part of his kindly chancellor mask, now he can be his own Sith).
