The plan would not work, because Excalibur mortally wounded Hook. Once the immortal ties are cut, he will probably still die. Emma is just too desperate, to realize that. Yes, it would. The magic, darkness, and HG magic would go into Zelena and then Excalibur would kill Zelena and she will die with the magic. Wounds from Excalibur cannot be healed and they will die.

So, Hook might die if the power left him, but then that's just the prcie Emma will have to pay.
