67mm thread ikelite 5508.45 port

About a year ago I upgraded to an slr for underwater. I have some old Inon Ucl-165m67 screw on macro wet lens' that i used with a compact camera. I was wondering a) is it worth using these with my 100mm canon macro lens. B) if it is worth it, how do I attach them to the 5508.45 port? I also have the modula ports that will fit the 100mm (cant remember the model numbers) that am using for the 60mm macro lens if that is easier to attach to.

Thanks
