Livers can come from live donors, they cut the liver in half and put half in the recipient and leave half in the donor and both livers will regrow themselves to full sized livers. If one half of identical twins needed a transplant they would be a genetic match, the healthy twin would be able to donate half of their liver. In this case, if the healthy twin is willing enough to swap identities with her sister to get her on the list then she'd likely be willing enough to be a living donor.
