Yea, I'd love the Walker bridge for the Garagin, or Titan to allow for Lower Decks access. The same would be nice for the Romulan Scimitar Bridge, or the default Origin Bridge for each faction slightly modernized, given a little Aquarius treatment with Holo displays.
Saw Ten-Forward, regarding interiors customization. Be however nice to customize through expanded Trophy Mechanic to replace Chairs, Desks, Rugs, Lights, Paintings, Artifacts, Musical Instruments, Beds, and others as they do in Ten Forward, Ready Room for Wall or Floor Trophies. If they allowed Trophies being acquired another way, with Zen, Lobi, or GPL & DIL, or something else. I think it be a nice to reflect more of the Captain's personality in those 3 rooms of Starship interior; if not changing textures, floor colors, etc..
