Possibly my last contribution for a while but hope it inspires as others have inspired me here (Barihawk, etc). If anyone wants to develop further, happy to send files. These are bridges I wanted but lack of original models.
Akira - retex of GalRefit
25C generic cruiser - retex of Gal
TNG era generic 'large' bridge (bigger than Ambassador, smaller than Galaxy). Retex of Excel refit
BoP - retex of Defiant (closest to Rotarran; originally did a Galor retex which works, but this is closer)
Vorcha - retext of NX bridge; again, thought industrial look very Klingon.
Reman - retex of Nebula (had closest bridge layout)
anyway, just some ideas....
