Considering Yukina not wanting to kill anymore, I can see her at first being one of the nurses aboard Whitebeard's ship. She'd be working her way up to becoming a doctor under Marco's tutelage alongside Deuce. Whitebeard enjoys bickering with his 'kids', so Yukina’s sass will be welcomed. However, Whitebeard generally has the final say. He’s kind of like Odin. And truthfully, I think Cipherpol won’t try anything with Yukina if she joins him.
Like Miyuki, I can see her jumping ship to join Whitey Bay as soon as Ace does for his own mission because of Thatch’s death and what it entails.
As for Law's crew, while Ikkaku-mun’s right, you're the only one who knows the ins and outs of Yukina including her special circumstances. You will probably have to explain why and how she became devoted to Law. The other thing you want to note is what Law may see in Yukina and her use to him. Because of her knowledge of flora, he may take some lip from her here or there. Only if it has to do with her expertise.
:3 Good luck!
