This has been done. If you are having humidity issues, it will help. Even without much airflow, the cold surface will snatch lots of water out of the air if it can. Whether it can or not is determined by comparing the ambient dewpoint with your liquid line temp. If the liquid temp is below the dewpoint, the humidity will condense onto the hx.
The latest examples of this principle are in the heat pump food dryer thread. Many ecorenovator members made working units that dried herbs, fruits, and even made jerky. The machines work great!
