How would you pull that off, and how would the structure benefit from that change?
I haven’t thought about it too much, but maybe show a shortened version of Ahsoka getting the map with no self-destructing droids, she takes it to the New Republic to entrust them with it, then they raid the ship and take it. There’s no footage of them taking it from there so it will have to be implied. I don’t know. But there is footage of Ahsoka having it on Home One I think.
Ahsoka hands it over to Hera during their meeting where they discuss the attack on the transport, which has to come after the raid. Apart from that there is no scene of Ahsoka on any NR ship if I am not mistaken.
But that problem aside, you could add a shot of the map on a pedestal to the cell that Baylan opens. The simplest way to achieve that might be to edit a still image of the map sitting on the pedestal on Seatos and place it in the foreground of the shot showing Baylan standing outside the open cell from Morgan’s perspective. To sell it even better you could add a digital focus shift from Baylan to the map or vice-versa.
