Didn't you see GitS? Motoko is naked... a lot. 90% is an exaggeration, but she's in the android buff in several scenes in the original movie. She also doesn't even wear pants until the second season of SAC.
Nudity in the movie is not that prevalent, and really not that sexy at all.
The nude scenes build Motoko's character as one detached more and more from the human world and its conventions, and they twisted the sexually charged content that was in the manga and made it much more interesting removing any "sexyness" while keeping the nudity.
When she isn't naked more over, she has pretty normal clothing.
In SAC on the other hand she's dresses with a swim suit 90% of the time, and it's a constant collection of tits shots and ass shots.
So to me it depends what they'll be going for, with this one; needless to say, i hope for the former.
It's an American made film ... of course it will have to be in English. Sooo now we need someone who can act in English, right? Well, the amount of Women who can head an action flick these days aint too high to begin with. Add to that the desire for this woman to be Asian American? That can tots happen! I mean .. if it's an IP like SW where the brand is so big they can leverage testing things like not-very-well-known talent (like making the MC a Chocolate British man).
This is a manga/ anime and that's like the nitchiest thing you can base a big budget film on. They need something to get the money people on board and Lucy Liu is the best bet for American Asian Female star power that I can think of ... and she's too busy with TV to be the head of a big movie (among other reasons).
So yeah, they go after the best bet you can have for a smash hit Female Action movie ... Scarjo (the woman whose "brand" made Lucy a hit that's more successful than any of the Avenger's post "Avengers" non-Marvel flicks in 2014).
If this was a big brand on it's own (like a hit YA novel or a SW level ip) then yeah, I can see the logic behind thinking it's a possible testing ground for Asian Women. But it's not. The movie is being sold to investors on the back of Scarjo as a Scarjo Movie just like EoT was sold on the back of TomC as a TomC Flick.
If they're smart they will either pull a EoT where they change the characters and settings and such but use the basic story and lore ... or they tell the story of a different character in that world from a different PoV that Western viewers can relate to ( I honestly think part of the reason it's taken Scarjo so long to agree to this may just be the story).
Again, they don't need a massive budget for this movie, and they don't need a big name for the lead.
This is why i think it most likely won't end up being that interesting, GitS is not much about the spectacle at all, and doesn't need a 100m dollars of budget to work.
Besides, you could have Batou be the one doing the heavy lifting in that sense, sincce Hollywood it's full of big white guys you could cast as him.
