Speculars can be coloured, so the Aeon specs will work for the chameleon effect. It won't change colour as the angle of the light changes, but it will suffice.
The Borg cobe textures can be improved one of two ways:
1. Remove the green blotches, and render the textures to a flat polygon with the same texture used as a bump map, and a few low-powered green omni lights close to the surface, then use the render as the texture.
2. Model the maze of pipes and greebles, with full lighting, render them, and use that as the texture.
Either way, simply painting the lighting on will always look like a cartoon.
2 models, with a casing of greeble, and innards of green glow, do not look as good as you'd think. I built a voyager style cube a few years back, with just such an arrangement. The inner part glared out the gaps, it didn't look too pretty, I can tell you. I never released due to crappy textures.
