Ikelite macro lens port with 67mm front filter threads?

Pardon my ignorance, but I am investigating options for a DSLR housing/port system. I was wondering if Ikelite (or 3rd party) offers a product that allows the 67mm front filter threaded wetmate lenses to be installed on the Ikelite flat ports (specifically for Canon 60m and 100mm macro lenses).

For instance I would like the ability to add an "Inon UCL-165M67 Close-up Lens" while underwater.

I know that Inon and Athena make macro ports that support these wetmate lenses for Sea&Sea and Olympus housings. What about Ikelite housings?

Thanks.

Sorry, but we don't support the attachment of 67mm threaded macro lenses to the front of our DSLR flat ports.

You may check out Backscatter's MacroMate accessory lens which is available for our modular flat port system.
