I actually have (in my humble opinion) a great and pretty simple idea for the Hux “hold” bit.
Hux starts his big speech, then partway through it we cut to Poe’s cockpit where we see the “loading bar.” When it finishes, Poe attacks.
You lose all the “tooling” stuff, but the humor is still there since Poe now cuts off Hux’s speechifying before he has a chance to finish. You can use the cut to the cockpit to stitch together the two separate longer bits of Hux’s speech, making it seem like he was never interrupted by the “I’ll hold” part.
Whaddaya think?
That may depend on what Hux was saying monologue-wise, which I can’t remember. What was he saying that wasn’t a reaction to Poe’s lines?
It could work though, but at the same time, it might be kinda weird to have Poe silent, but if the loading bar and Hux scene switching is fast enough, edit wise, it may work.
