How can I change the moon texture within the Creation Kit?

[Ruadhan2300]

I don't know if it's even possible.

But for a tentative plan in one of my mods, I want to blow up the moon as a scripted event.
The idea is that basically you fire off some giant laser or missile, and there's a huge flash in the sky, and when it clears, the moon texture has been replaced by a version that's been blown up (giant fragments and debris)
If it's feasible to do it, I'd like to use several successive versions over the course of several in-game nights. culminating in a band of small debris across the entire sky with only a few large fragments still where the original moon was.

I know how to find the actual moon texture and swap it out manually, but I need to keep the original until the scripted event.

Can't find any useful references in the Creation Kit, I was hoping someone here might be able to come up with a way to do it.
