Any character can open your rotw regardless of which one earned them.
Are you asking if they will both get a transmute geode? Because your rotw are account wide from your mail so any character can open them. However... once per day per account only will you get the garunteed gold geode.
You could still get more through rng. But only one per account is garunteed.
