Spoiler:

Personally, I really like this suggestion. I really think this is the best English option that sticks to the spirit of how the Japanese pen name was formed.
-It takes the meaning(vs the reading) of the name, from Ange into Angel
-changes the spelling from Angel to Anne Jill (since Ange is an odd pronunciation of her Kanji to begin with, this is true to the Japanese original),
-and reverses the positions
In short, it keeps all 3 elements of the original "puzzle."

The best alternative to this would be the "lazy" route.

Regarding the Siesta/Chester, it's an annoying problem. I really think that "Chester/Chiester" is too easy of a hint. At the same time, without knowledge of how Japanese is pronounced, namely "see" turning into "chi," it is difficult to make the link between Siesta and Winchester.
Personally, despite knowing basic Japanese, I had to rely on other clues to confirm the sisters' identities. I never even noticed the name Siesta itself.

Spoiler:

By clues, I mean things like how all their numbers were gun serial numbers.

There would almost have to be a double-take in the script where someone like Battler mishears the name and gives a goofy "did you just say 'Chesta sisters?'" kinda thing. This is a pretty common pun set-up in anime, so it might pass in a VN.
