It probably is just me, but I can't help but think that there's no way (even if it was Khan) it really could be a remake. Not in the literal direct sense. Even Star Trek wasn't. Thematically it can't work at all, so he would have to represent something else. And fashion a different story out of it.
I mean, I know in Trek we do deal with repetitive plot elements, themes and very definitely idea rehashes and I know we have done even since the days of TOS and it's umpteen parallel Earth stories, but in terms of a direct remake I still don't quite see it happening that way. May be wrong of course.
Nemesis was obviously SO clearly a clone it couldn't hide it if it tried to, but certainly in Star Trek those elements are actually more like the 'B' story of the film and not at the fore of it.
