If I substitute fruit juice for some of the water when I make mochi, will that make the mochi taste like the fruit?

So I found this recipe for mochi: https://www.youtube.com/watch?v=rWjdBDe9dS8&t=133s

I noticed it didn’t have any flavoring besides just “sweet.” I want to make it taste like lychees. It says 3/4 cups of water. If I instead do 1/2 cup of water and 1/4 cup of lychee juice, will it taste like lychees? Or is that too much/too little juice? Any help is appreciated.
