What would have happened had all of the Huns not survived the avalanche?

I thought of several possible outcomes, based on the premise that 花木兰 is abandoned after having her true gender uncovered:

(1) Chi-Fu & the rest of the army decide to simply sweep 花木兰 under the rug and not mention her to the Emperor. In this case, if the Emperor rewards them with any tangible items, some of them may decide to (possibly secretly) give them to 花木兰 after receiving them.

(2) Someone (most likely Chi-Fu) decides to tell the Emperor about Mulan, and the Emperor decides to summon her to the palace and honor her for her actions.

(3) 花木兰 (and possibly other members of her family) is summoned to the palace, but to receive punishment instead of honor for her actions.

Which of these do 你 think would be most likely?
