Part of the reason why I personally think Carrot has the chance to do something else is due to her condition after her fight with Perospero.
Like she was definitely injured and all that but I feel like it's nothing she couldn't recover from in the time between the end of her fight and the end of Nekomamushi's. She wasn't even white-eyed knocked out like some other characters were. Especially compared to Usopp who's been running around Onigashima with a broken skull just fine. I do feel it is at least plausible that she has the opportunity to go Sulong one last time before the end of the arc.
She only turned Sulong once and was still conscious after her fight and was jumping and hugging Nekomamushi after his.
