yeah, but i just think that Jyn Erso is a particularly shit fake claim (no offense)
she is not that known by general audiences, since Rogue One didn't get that massive box office
her character is pretty basic, not a marksman, not a jedi, not a sith, not a droid, just a normal soldier and doesn't even have a huge personality like Han Solo for example
because of that, the host could give Jyn almost any role
and because less people know her, it's an "easy" fake claim without getting a lot of risk of being cc
and if there were options of fake claims for scum, i think you would've avoided choosing Jyn
