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?
