Yes, no problem. You may have to rotate/adjust the loops to get the spacing wider depending on how they were set up and you will get less insertion loss too if they were originally set up for close spacing.
Depending on where and how they are used at the site, you may want to set up 4 cans with those frequencies (as a Q2220E) and use the 3rd can on each side to give it a good pass response (by making the 2 notches of the Q can symmetric around the pass frequency) or tune the notch to another frequency that may be causing problems or prevent potential problems.
