It's too early to tell, the four girls you mentioned haven't even been shooting that much. Gal went from 8 scenes per month last year to 4 this year, and her scenes haven't been very relevant. Chanel's had to have surgery for endometriosis, which has affected her productivity. Chloe hasn't been shooting at all, just 5 scenes this year. And I doubt Jennifer wins it again, it took a massive effort from her and Spiegler for her to win it, and she hasn't been as prolific this year either.
Girls like Anissa, Rebel and Skylar will definitely be ignored, but Angel could be one of the nominees if she starts pumping out more scenes. She's only shot for top studios this year (Brazzers is trash but they still have their reputation) but there haven't been that many scenes. But yeah, there's still 6 months until AVN 2027, we'll definitely have a clearer picture towards the end of the year.
