Bismillah hir-Rahman nir-Rahim !
(Fatwa: 218/124/H=1433) No, you cannot do so because this nikah is haram. Your mother (who is nani of the boy) became his foster mother and you (mamu of the boy) became foster brother of the boy and your daughter became foster bhatiji (niece) of the boy. It is haram to marry one's foster bhatiji as it is haram to marry one's nasabi (genealogical) bhatiji.
