Well I do have a suggestion for your rainbow variant that you're giving to Jimmy: Make Hendrix the red alert klaxon. That said, it does look like a pretty simple floor plan for the bridge part, so unless you're planning an excalibur release, the basic plan shouldn't be too difficult, granted I'm not too knowledgeable when it comes to interior models. From what I understand, modeling the bridge isn't the hard part, it's getting it all to work that's hard, but I wish you the best of luck.
