Since I couldn't find anything similar enough (or anything to my liking) between the regular alternative crosshairs, I decided to make one myself:
It's a very simple cross, with a thin and black outline for increased visibility in brighter areas.

Just put it in your Xonotic/data folder, it will replace one of the existing crosshairs, you'll notice when viewing the player settings screen @ multiplayer menu.
