Her father may possibly well die before the arc ends, also vegapunk ask the straw hats to look after and she is an admire of nika which is luffy.
It is more likely for Kuma to be alive at the end of the arc than dead. His memories in his paw pain orb are slowly returning to him, the system that made him a mindless cyborg were shut off, and he has been knocked out but not fatally wounded so far.
So I find it far more likely that once they escape Kuma starts regaining his memories, the two Vegapunk feel obligated to restore him, and with Chopper and Franky help do so. The Straw Hats thank Kuma for his help two years ago, and he learns that Luffy is Nika. Tears shared between Father and Daughter reuniting at last. Then they go off to join their comrades in the Revolutionary army.
Luffy doesn't really let young kids join his crew, since Shanks didn't, or he would have let Tama join.
I also see Atlas acting as a donor for Kuma for spare organs, requesting Lilith be allowed to join the crew and see Laugh Tale. Lilith being the last Vegapunk feel obligated to join the crew to see through Stella's wishes.
