Unfortunately no you cannot.

Different sized ducting is used for evaporative and ducted reverse cycle air conditioning. And the outlets need to be located in different parts of the room.

Evaporative air conditioning outlets are located away from external walls as the cool air will be pushed from the outlet across the room to the open doors and windows.

Ducted reverse cycle outlets are located close to external walls so the treated air moves across the room back to the return air grille located centrally in the home.

Anyone who says otherwise is happy to sacrifice the proper functioning of your air conditioner in order to get a sale.
