If it's going to happen in the near future, it seems most likely to be a goalie. There definitely are athletes who have the size + athleticism - look at the WNBA. If you ask me whether I think an athlete on the level of A'ja Wilson or Nneka Ogwumike could make a pretty good attempt at it, I'd say they could. (Tell me a person with Wilson's footwork couldn't skate, lol). But the pathway to being a professional athlete in some other sport seems a heck of a lot more clear, and hockey is a really inaccessible sport. And if there were more professional basketball level athletes involved in hockey, it would be even more difficult.
I've seen some basketball athletes (especially on the girls side) doing lacrosse instead of track in the spring completely change the game as middies. And I've a few who would good enough to play with the boys as midfielders. But it's way way easier to teach an athletic kid to pick up ground balls, cradle, catch, and pass in a few weeks than it is to get them on skates, and it costs nothing. And those girls already know how to box out, lol. Girls basketball can be really physical.
Idgaf about gender roles or cultural crap. Just talking about athletes.
