Maybe Gauri ki nayi pehchaan will be her daughter. She will be pregnant, so she wont really die, but will become brain dead. Ipshita will be shocked to know that Gauri is pregnant, but Shiv will ask to keep Gauri alive since he wants Gauri's nishani. Once the baby is born, ... Im not sure, they can bring her back to life, or maybe kill her.. but my focus is on the kid..
meanwhile, Shiv and Ipshita will marry, and they will raise Gauri's daughter also along with their kids.
Fast forward to 20 yrs later...
Gauri's daughter will look just like Gauri.. and that will be Gauri's new pehchaan.
2nd option, did u see the movie Dil ne jise apna kaha.. (Salman, Preity, and Bhumika Chawla) .. maybe like that they will do a brain/heart transplant of gauri's into someone else and that person will start having feelings for Shiv.. (ok, lets make it a heart transplant) .. but will Shiv recognize that??
Ok, Im all over the board with this.. very dumb ideas...
but just wanted to get it out of my system
...that feels so much better now...
