Was Shego supposed to die in So the Drama?

I read somewhere (I don't remember where) that Shego was originally supposed to die after *a VERY OP* Kim kicked her into that tower and made the tower collapse. But they kept her alive because they thought that Kim killing Shego would be too dark for Kim's personality (the smile she makes after kicking Shego doesn't help, either). Either way, I'm glad she didn't die. I 愛 Shego, and she's my お気に入り character in KP.
