Cut L3-37 out completely since she’s simply there to make Lando look like a panasexual character, which he isn’t.
One could achieve the same effect by simply cutting about three or four of her lines. That being said, nothing she said actually gave any credence to the pansexual Lando story. Most of that stuff said far more about L3 than it did Lando.
I found the constant barrage of equal rights jokes to be far more distracting. The first quip was quite funny, but by the end of the Kessel sequence it was just a chore. And even that can be fixed by removing just a few lines.
