From what is visible in the newer art, it won't be styled to look like part of the ship. It will be more than a plain, flat color, but it will look like a separate docking platform.
Again, I think it's only "too bulky" if, narratively speaking, it's supposed to be an armature for displaying an inactive ship. If the intent is to make it look like a proper docking station for a functioning vehicle that is actively transporting Xandarians to the pavilion, I don't think the same rules apply. Of course, it could still end up looking terrible if it's just not aesthetically pleasing, but if it's supposed to appear to be functional, I don't immediately think it looks too big relative to the size of the ship.
