Your two mature adult cats likely will not change too much as their personalities and relationship are well established now. They will likely continue to have their little tiffs now and again. My main concern is the litter box tiffs. Some cats will get a real litter box territorial aggression and then will not let another cat share it. So if you have only one litter box, suggest you get two more----general advice is: one for each, plus an extra. This usually fixes that sort of problem, as long as they're not lined up in a row! Put them in different, quiet, and low traffic locations. Oftentimes, a covered litter box gives the cat more security that it's not going to be ambushed. On the other hand, some cats don't like a covered box, so get just one
of those to see if that makes a difference.
Play with the cats with an interactive toy such as "Da Bird" (fishing pole type of toy with feathers on the end) for about 15 mins. twice a day which will drain off any pent up aggression usually. Also reward good behavior when you see them together peaceably with a few treats and kind words in sing song voice such as "goood kitties!", so that they come to associate being together and behaving well is a good thing. Hope some of these suggestions will be helpful. All the best!
