Actually the proportions of current Ambassador bridges is not very canon to "Yesterday's Enterprise". Since both bridges are not canon at all, there's no "going rediculous" if you adjust the width and space of them.
Also, there're no extra crews on the Enterprise-C bridge, and only two on the Yamaguchi bridge. The animations of staff crew should not need to be remade. I don't think that you need to redo all animations.
The Ambassador bridges are one of the least voted items in
current BCfiles poll, along with Mirada and Galor bridge. It still has a lot potentials to be better. (No, I haven't vote yet.)
Anyway, you are the bridge developers, and you have the right to decide what to do... or do nothing. I just propose my ideas. I still thank all of you for the great work you have done during these years.
