I'd really like to see more bridges for FED ships based on actual bridge designs seen in TNG and DS9.
I was watching some old TNG episodes and would love to have a bridge like the one for the U.S.S. Hathaway from "Peak Performance" or one like the U.S.S. Sutherland from "Redemption, Part 2"
I mainly like these bridges because they're smaller without looking like a knock-off of the Defiant's bridge. We have too many MASSIVE bridges that look like they belong on a ship that's 10 times bigger than a Galaxy Class.
