Your idea is nice.
I want this scene
Ruqu, Hamida and Salima go to Delhi because its Humayun death anniversary or Ajmer Sharif for a month
But they leave Rahim behind as he is too small to go so far. Jodha promise to take care of him.
Rahim is naughty and make many farmaish
-One day i want to play with you and Jalal in garden
-One night he get bad dream and start crying and say take me to Jalal. I will sleep with him and you both as i am scared. So Jalal-Rahim-Jodha sleep together that night
-Another day Rahim has heavy fever and Jodha and Jalal worried. They stay awake all night taking care of him
-Another day Rahim say lets play hide and seek and blindfold Jalal in garden(near Taj Mahal)
and Jalal catch Jodha by mistake
- Jodha teaching Rahim hindi and Jalal teaching him sword fight with each hidding and observing the other
-Rahim asking Jodha i want a brother to play with, asking how to get brother to Jalal and Jalal accepting defeat that he an emperor lost to rahim and cannot answer his questions and Jodha feeling shy and running off
- Jodha-Jalal having fight and Rahim resolving it and making them say sorry to each other
