I don't think they are going to redeem Earth-2 Laurel  but they could bring back the original Laurel Lance by putting her soul inside Black sirens  body. Constantine was able to return Sierra soul to her body in season 4. Now Sarah has contacted Laura’s Spirit and Oliver has found someone with an identical body. Not to mention that in the comics rag man's cloth absorbs the souls of the wicked  to repair itself. If Earth-2 Laurel’s soul is removed from her body or her mind is erased they'll have all they need to bring back the original Laurel. That way she will return with the powers of Laurel Earth-2  but the soul and memories of the original Laurel.
