Sigyn Fancast: Gugu Mbatha-Raw

Ever since it was announced that Gugu Mbatha-Raw was cast in the upcoming Disney+ Loki TV series, I have been hoping that she will play Sigyn. So far no information has been released as to what character she's playing. My hope is still on Sigyn but even if she's not, I can still fancast her as the Asgardian Goddess.

Update: I forgot to include a picture of Sigyn.

Although, I would change a few things about Sigyn such as not making her weak and submissive as she was shown in many of the older comic books. I would still keep her as Loki's love interest but she would be just as strong, intelligent and magically powerful as he is. I would love to see what kind of trouble (and fun) those two could get into.

What character do you think Gugu Mbatha-Raw will play in Loki? And do you fancast her as Sigyn?
