Need help with creative name suggestions!

So, both my father and my husband’s father have passed away. My father’s name (Uday) means sunrise, and my FIL’s name (Salil) means water. I would love to name my son after both these men, without taking their exact names. Is there any name in your language/culture/ knowledge that combines the two meanings?

Maybe you have suggestions for easy to pronounce South Asian/ Indian names? We are completely stuck on names, any help would be much appreciated!
