It seems likely that they would make various things that RJ merely suggests somewhat more explicit, like for instance showing various Aes Sedai in romantic/sexual relationships with other Aes Sedai or with their Warders. Mat's womanizing might more explicitly involve sex as well.
By the way, I never saw the WoT swearing as 'fake' or 'comparatively innocent', just as good immersion in a fantasy world - RJ makes clear enough from the reactions of other characters how offensive they find the various expressions. In real life, too, other languages may have swearwords that are quite offensive but seem harmless if translated literally into English, and the other way around (the Spanish in particular seem to have a remarkably high social tolerance for swear words and expressions that sound really vile to any outsider).
Anyway, but on the other hand, I'd expect them to remain faithful enough to the books that it would still be a far cry from Game of Thrones. The sex and gore are part of that difference, but a more important one is the much slower start of WoT's story. At later stages the story may become fast and spectacular enough that you could try to emulate GoT, but even if they do compress the story somewhat, it seems inevitable that they'd have to get their viewers to appreciate a slower and less controversial plot in the first season or two.
