No, you can't easily switch the 'party finder' argument around. What is easy however is to understand the reason why you can't: the requirements to queue in duty finder are just level and/or item level, whereas the requirements to join a party finder group can be whatever you want them to be, from learning/practice to all the way up to perfect skill or even parsing competition. So if you only expect level-ilevel then duty finder is the tool. If you expect anything else then party finder is the tool: make sure you explain your requirements properly.
