Think of the passive radiator as an alternative to a port.
The passive radiator and driver work together with the volume of the cabinet. It's a system and you should not attempt to alter without a proper understanding (aka speaker analysis) of where you are starting and where you are going.
If you are getting an itch to DIY, you'd be better off building a new subwoofer from a kit. :) Lots of good options at Parts Express.
