To be fair, putting even a little thought into the drama could improve it greatly. America has a tendency of focusing on "big" drama, which is one thing the original put too little focus on.
The whole concept is about escaping from a MMO that will actually kill the player, but it doesn't do much with the idea in favor of petty, often completely idiotic squabbles. Like nobody wanting beta testers because they'll get the best items.... you know, in a game that can actually kill them, they want to not give the best items to the most instrumental people to their survival..... -_' but that's where the drama goes. It'd be fine focusing on smaller relationship drama, in fact I'd prefer it, if it weren't so unbearably stupid. If an American version cuts that kind of bullshit and focuses on character development [as opposed to all character progression occuring in between episodes] or even just ignores the idiotic conflicts in favor of big dumb 'splosions, it'd actually be less insufferable/boring.
It's not difficult to improve on something like SAO. Will they? Probably not. But it wouldn't be difficult.
