Just posting to say that I have put this project on hold indefinitely due to Sean making an excellent original bridge for the Stargazer. That old beauty will fit the Constellation well and I full support it. Sean, if there is anything I can do to help, let me know.
I will probably start prelims on my Akira bridge now. This will be tough since it will only be a re-texture with instructions on how to set up a unique bridge. This is to fit with Mark's wishes that his Ambassador TNG bridge not be released outside of KM1.0. Therefore, the Akira bridge will only be for KM1.0 users

. It will be much easier to set up, and not really many changes will be made to textures, just the MSD at the back of the bridge. The Ambassador TNG is exactly how I picture the Akira to look.
The Centaur bridge will probably be done the same way, since I intended to use the Excelsior bridge for that.
I'll post a WIP for the Akira in a few weeks.
