First, really good work, second, why in the name of Primus did they stick the Dedication Plaque up there? with starfleet's track record, it'd fly off and thump ole Jimmy boy right in the pumpkin
@Rekkert ironically as a means to keep myself occupied putting 3m blue painter's tape in a box, i kinda came up with a similar sort of thing, only it was the NX-class up rated to 24th century technical standards. Alas, the headcanon starfleet exists mostly in my head and as a spreadsheet of factoids lol.
If it helps at all, the gfx folk always said the bridge modulers were...well modular so they could be swapped out, so your idea of a temporary bridge works. Picard did kinda root around in the junk drawer for his fleet.
