Those caps should work as long as the voltage rating is high enough.  I like to see at least 600 volts.  You may want to pot it in the can with some silicone RTV so vibration doesn’t cause the leads to flex and break.  Regular RTV outgasses acetic acid while curing, which is corrosive, but there’s an electronic grade that outgasses ethanol vapor.   I used that to keep bigger capacitors from vibrating and breaking their leads when I worked for Honeywell designing temp control circuits for ThermoKing truck refrigeration units that see a lot of road vibration.

What are thoughts on using hot glue gun glue for potting in condenser cans.
