Two part question... Any advise would be amazing!

1: Are Mitsubishi MSZ-GL Series Wall Mounted Mini Split Indoor Units compatible with the Mitsubishi MXZ-3B Series Outdoor/Condenser Units?

2: Mitsubishi list the following indoor unit combination as compatible with a 30k btu tri-zone outdoor unit (MXZ-3B30NA-1)- 9k+12k+15k. What potential problems would I have if I ran 9k+12k+18k (Im wondering if I can add a 9k unit to my existing 18&12k units on a 30k condenser).

Thanks again for any input!
