Question About Prepping Two Soups at Once

Hi all, great subreddit. I would like to prep two soups at the same time, cooking one immediately and the other the next day. Will this work? Can I chop the veggies and then put them in the fridge for 24 hours without losing much flavor? Also, any recommendations on two soups that would have similar ingredients but be different enough that we won't have 12 quarts of the same flavors?
