I'm Planning on lighting both. As far as beveling the sides and adding a step, I wasn't going to go that far. What indentation on the lower aft hull? I hadn't run across that yet, oh and the tail fin needs modification.
If one really wanted to go all out, one could scribe panel lines and add impulse engines as seen on some renderings on an internet image search. Although, I thought the BoP was sub-light, so what's the need for impulse engines? The original show model doesn't have impulse engines or panel lines. "OK Chewy, lock in the sub-light engines". Sorry, wrong Galaxy and time frame.
Here is my crude lighting circuit. The LED's on the wires (yellow, red and blue. I could have sworn I had green in there) will go to the engine nacelles, Although, again, the original model just had a white glow, but were's the fun in that? I will frost the nacelle caps and hopefully the different light colors will have the results I want them to. The rest of the LED's will bathe the interior of the hull for the windows (I added blue just to see what that would do, probably nothing). I'm going to paint the interior of the hull with chrome and line the windows with wax paper to diffuse. I will leave the senor holes black by placing a piece of styrene behind them.
OK, so I guess I've officially started.
