Kidman, Dunst, Fanning
I do not want to prejudge the film, and I will give it an honest shot if and when I see it, but the filmmakers seem to have cast "names." They may all end up fitting the parts, but part of the appeal and effectiveness of the original The Beguiled derives from how the filmmakers did not cast the female parts based on "names." Once director Don Siegel and star Clint Eastwood decided to make the film (they had recently made two movies together, Coogan's Bluff and Two Mules for Sister Sara, and were mutually admiring friends and colleagues), they did not try to fluff up the cast with any notable names to "complement" Eastwood. Geraldine Page was an acclaimed actress, especially on Broadway, but not a movie star with popular appeal (despite having once starred opposite Paul Newman, a decade earlier in Sweet Bird of Youth). Elizabeth Hartman had enjoyed a couple of notable roles a few years earlier, once opposite Sidney Poitier in A Patch of Blue (1966), but not recently. And everyone else was anonymous. And because the actresses were cast simply because of how they fit the parts, there is a freshness to the casting—a lack of commercial contrivance that permeates the entire entity.
Coversely, Kidman/Dunst/Fanning sounds about what one would expect from filmmakers seeking a "high profile" cast that will generate publicity with the media and within the industry. That is not to say that they will not fit the parts, and perhaps they will all be great, but casting three "names" for the female roles suggests the possibility of your typical Hollywood procedures. We shall see.
Incidentally, this matter came up in an interview with Eastwood in 1974; see this video from the 18:42 mark through to the end:
