Well, let's not get carried away. There's a limit to the amount of changes that can be brought to the universe at large without alienating those ever-so precious casual readers who can't handle simple things like cast lists.
But, seriously, it wouldn't be good for the book line if a potential reader only familiar with the film and TV series picks up a post-Destiny book, reads the back blurb and hasn't a clue what the hell is going on. Shaking up the characters is always a good thing, but if the general setting becomes unrecognizable, readership would be expected to drop.
Still, I can't wait to see what does get messed up.
