There’s also a shot of the torture chamber where Chewbacca is kept. It might work to have Rey see that when she senses Chewie is still alive.
I’m with Hal on this one. I think it would feel weird to imply that Chewie has been tortured - but not actually see Chewie either way - and they Rey be all smiley and happy. Huge tonal clash.
Although, it might be cool just to hear an echoey Chewie roar in the distance when Rey senses him, to involve the audience a little more in the realization.
