They *won't* ruin Fluttershy _*or*_ Twilight.
Firstly, these concepts aren't final and most likely will change before G5 rolls around (which won't be until at least a couple more years, if not later)
Secondly, the Twilight and Fluttershy
Finally, if the next iteration of MLP _does_ ruin the names of Fluttershy and/or Twilight (or any of the other characters for that matter), Hasbro would lose a large amount of profit and potential for profit growth, so they'd want to avoid that at all costs
