I like your enthusiasm! If it were me, and I was determined to run taller tires, I'd match them. You won't know until you run it, but I'm betting you've introduced some healthy understeer in that configuration.
Since the others are new, consider selling them and buying the matching set? Sorry, I know that's not what you want to hear. :/
