Except, isn’t the whole point of Rogue One that the people who got the plans aren’t really “special”? They’re not Jedi, or famous figures. They go on a secret mission, and they all die at the end, without anyone learning who they are. They’re just a bunch of regular folks who took a stand and achieved something incredible.
Rogue One is all about how the non-famous, forgotten people in history can still make a difference. The whole point of the movie is lost if Jyn Erso & Co. become legendary figures themselves, imo.
Agree, I feel the idea of iconic StarWars characters plastered on wall will degrade the film somewhat. I get Luke is a legend known throughout the galaxy but even the idea of directly seeing his image this was may feel a bit odd as a fan.
