Adding ricotta cheese

Toast

I'm a lemon lover and a beginner baker. However, there is a great Lemon Chess Pie recipe listed on the KAF website that I would like to try. I would like to know if I could add some ricotta cheese to the ingredients. Also, how much of the ricotta  should I use and any additions or subtractions would I need to make from the recipe? As always your thoughts, comments, suggestions are always appreciated. God bless.
