I KNOW THAT THERE ARE ONLY 7 Princesses of Heart that have the power to final door.

 

1. Snow White

2. Alice

3. Cinderella

4. Aurora

5. Belle

6. Jasmine

7. Kairi

 

now ... what if we had 10 PRINCESSES OF HEART and that Maleficent had got it wrong! and that she actually needed 10 princesses of heart

 

8. Rapunzel

9. Elsa

10. Anna

I really doubt they'd introduce a plot point like that this late in the series

Elsa is a Queen, sorry. 

Maybe Merida? 

Why would that happen?

Why should they even need more princesses of heart? And Elsa is not a princess u.u

Oh, jeez, Being a Disney Princess automatically doesn't make one a Pricess of heart. You need to have a heart completely devoid of Darkness. Ariel and Mulan prove this. and Alice proves that one doesn't even need  to be a Disney Princess to be a Princess of Heart. Therefore any Princesses who join the ranks are not, and will never be Princesses of Heart. Theories are fine, but it is pointless to theorize about something that will never happen. They may get into the game, but they will not be Princesses of Heart. End of story.

"The χ-blade was splintered into seven fragments of pure light, which eventually become the seven princesses' hearts"They'd have to change this to add more Princesses of Heart, so I don't think it will happen

If they did add another Princess of Heart, it would probably just be Rapunzel

No if they added another it would be Tiana from Princess in the Frog because she was around prior and she deserves some firetrucking recognition for once
