What would happen if an angel dies?

[Dragon Ball Gus]

So, we know that when a God of Destruction dies, the Kaioshin dies with him, and we also know that when that happens, the Angels inactive in the universe he/she lives in. But one thing that I've always wondered is, what exactly would happen if the angel him/herself died? Give me your best theories.

The attendant angel can presumably be replaced. We don't have any specifics as to the species of entity that Daishinkan and his progeny hail from but I doubt they're the only ones in existence. Who knows? Maybe they're either inducted or enlist into serving Zeno's celestial kingdom. There could be some trainee angels looking to make a name for themselves by becoming the attendant and adviser of a prominent Hakaishin. Admittedly, it does seem peculiar that all of the angels serving as attendants happen to be related to Daishinkan personally. Is the production of their species comparable to Namekians somehow whereby they originate from a single self-reproducing source? We know there's such a thing as female angels amongst their ranks, suggesting that two sexes do exist.

All of this is just a guess, of course. There's still a lot of blanks that need to be filled in regarding angeldom in Dragon Ball.

I beleive it can happen as there was no sign of the angels from the erased universes, a reason why I thought the Grand Priest was plotting something. Then again they could just go to an angel dimension and have replacements if they can die for real.

If they can die at all. You would assume that the species that is above both the Gods and the mortals would be immortal.
