I have actually always wanted to put in a "flashback" mission that took place on the ship during the Pike era. Now that would be worth the extra work.
Also, I'd rather not go into too much debate about little things like the mirror from The Deadly Years. I'm going to have to pick and choose some of the smaller details to satisfy both the majority of fans and the "accuracy aficionados". After all is said and done, I want this to remain a fun project for myself and the fans of TOS.
I sat down and watched The Cage twice yesterday (both cuts) and the alternate cut of WNMHGB from the last disc of the TOS blurays and I would love to see Pike's ship fleshed out. The more subdued color scheme, the nifty Captain's quarters on deck two, and one of my favorite Trek uniforms...that would be incredibly neat.
