Alpha pattern/ granny square help!!

I am super new to crocheting and now that I’ve gotten a good handle on all of the basic stitches I’m ready to start on my first project. I want to make a pair of granny square pants that have a patchwork look. (See pic for reference)

While looking for different granny square patterns, I discovered soo many cute alpha patterns that i would love to incorporate into my pants. Is it possible to crochet a 4 or 5 inch granny square patch using an alpha pattern? Hopefully this makes sense😅
