I like Adria Arjona, but I think she might be slightly too old for the role. She's currently 33, and the new WW movie probably won't start production until 2026 or 2027 (maybe later).
I think that Gunn will probably want an actress in their late 20s and very early 30s (so about 27-31 years old) at the start of production. For example, Gal Gadot was cast as WW in 2013 when she was 28.
She was the quasi love interest for Boyega in that Pacific Rim sequel that bombed 8 years ago? She was fine as hell. Like super fine
But yea her window kinda passed. Scarlett was 25 when she debuted in Ironman 2 as Black Widow. Brie was 29 when CM dropped.
