You know, those red Emperor guards are pretty useless... while they are kinda cool looking, is there the possibility of just removing them altogether?

From a filmic POV (don't show a gun on the wall unless you intend to use it) and even a story POV (the Emperor doesn't even NEED guards, as he can read minds [of those plotting against him] and is a Sith Master) the guards are pretty useless - unless Ady or someone wanted to make a sort of Praetorian Guard and have some BLACK or very dark RED stormtroopers (twice as dark as the red on the current guards) - say one of the platoons or the front row of troopers on both sides when the Emperor first arrives at the DS.

I also sense some possibilities in regards to placing the tower in the center of the dish: you could make a panning camera shot (using a fish eye lens or something close to it)

(1) starting off with the tower in the center and the beams coming out of the dish around it
(2) the camera tilts upwards to follow the beams as they converge far above the tower
(3) when the beams come together, the singular beam streaks out and the camera continues to move up and follow it as it moves from left to right, destroying many rebel (and maybe later, rebel and Empire) ships.

I'll whip up some storyboards...

Also, could the Emperor's tower be reshaped to look if not like the jedi temple, than like the Imperial symbol itself? Like an octagon shape at the top tip of the tower, with an extremely larger version of the TIE cockpit window so the Emperor can see directly what the DS is destroying ...

It could look like a crown mixed with the temple and imperial symbol, with the spires going up the edges, and antenna dangling below to resemble vines, as if it was ripped and propelled from out of the ground...
