Okay guys. You all have made up this type of ending. Basically, Anna doesn't thaw, and Elsa never recovers from the incident. This is a FULL alternate ending, featuring my "Do You Want To Build A Snowman" Reprise.
#ALTERNATE ENDING
Anna: NOOOOOOOO! (Freezes as she saves Elsa, just like movie)
[Hans gets knocked back]
Elsa: ANNA!
[Sings my Do You Wanna Build A Snowman Reprise, which I'll link at the bottom]
Kristoff: You can't do anything, Elsa. She's dead.
Elsa: NO! She could not be dead!
[Pabbie comes in, observes the frozen Anna, and shakes his head]
Pabbie: I'm sorry Elsa, but you killed your sister.
[Elsa starts bawling her eyes out, screaming. Kristoff tries to pull her away from Anna]
Elsa: NONONONONO!
[Takes last look at Anna]
MANY HOURS LATER
[Hans looks at frozen Anna. Elsa, heartbroken, having lost the will to live, looks out the window, and sees Hans shatter Anna with his sword]
Elsa: NOOOOOOOOOOOOOOOOOOOOOOOOO!
[Elsa runs out, and confronts Hans, shaking all over, crying]
Elsa: Now what do you think you're doing, Prince Hans? You lied to me. She only died when...when...
[Elsa becomes untranslatable, she's crying so hard]
Hans: I only was going to marry Anna to be able to kill you, Queen Baby.
[Elsa freezes Hans's heart]
Elsa: Maybe THAT will teach you a lesson about lying.
[Runs off back to the castle]
#THE NEXT DAY
[Remains of Anna are getting buried, Elsa doesn't come, it's too painful for her, knowing that it's her fault]
Elsa: I wish that Anna was back...
[Starts crying again]
Pabbie: She did constitute an act of true love...why isn't she alive?
Elsa: Because Hans shattered her with his sword.
[Pause, with only Elsa's crying]
Pabbie: I can summon her spirit back.
Elsa: You can?
Pabbie: Yes.
[Next thing they know, Anna's ghost is there]
Elsa: It's wonderful...but just not the same.
[Rebuilds Anna's ice sculpture form, and starts crying over her again]
Pabbie: Why do you want that ice statue?
Elsa: It's the real Anna!
[Statts crying so hard, nobody in the kingdom can't hear her. But, next thing she knows, she hears a familiar voice]
Familiar Voice: It's okay Elsa. I'm here.
[Looks up, to find Anna looking at her with a comforting look]
Elsa: ANNA!
[Hugs her, crying, but this time, out of happiness]
Anna: What did I miss?
Elsa: Your funeral.
Anna: Let's go surprise Kristoff and Olaf.
Elsa: Yeah!
#A FEW MINUTES LATER
Kristoff: I wish Anna was here to see this kingdom so beautiful,
Olaf: I also hope Elsa will recover. She seemed pretty upset when we last saw her.
[Sven looks behind them, and bolts to a couple of figures. Kristoff and Olaf look, and notice Elsa, who looks like she's been crying a lot, but happy, and ANNA]
Kristoff: Anna! You're alive!
Olaf: Anna!
[All of them hug Elsa and Anna, and the rest of the movie unfolds the way it did]
