Brand recognisability matters, and I think that not only Valkyrie should look just like Tessa Thompson, but Heimdall as well. I'm not sure what is Tessa Thompson's character's name, but if she's Brunnhilde, I'm certain that Jason Aaron could find a way to explain the change. This film will breakout hard, so having Valkyrie looking like she looks on Thor: Ragnarok (both when it comes to Tessa's likeness and costume) will benefit the comics in the long run.
There's no reason for Valkyrie or Heimdall to keep being white. Their most famous iterations are already quite different than the old comics. So deal with that.
