Absolutely! It will change the size of your finished design though. I like to use the calculator here: https://www.yarntree.com/java/xstitchcal.htm when I am considering mixing things up. Good luck! (I am not an employee of ECS just a fellow stitcher.)

I can't believe it but in digging in really old stash found a table with stitches to inches and count size. I don't remember even buying it. I will be using it I assure it. By the way, that is a beautiful pattern. I am always in awe of other stitcher's projects and feel like a simple simon.
