Ive done the same with my Extra PA recipe. Its a simple recipe and I did an easy switch with the yeast from 1056 to 1272. In my next batch I'm planning on trying it with a 1318 or a 1335.
I'm also trying to do the same with hops but the schedules seem to vary too much so I've been sticking to very similar recipes but using single hops.
I want to make my own recipes, but in order for me to do that I need to understand the ingredients. Plus there is no downside, I get to drink my testing material
