That won't work; the basic bundled port has no threading and is approximately 100mm wide on the inside, where threading would go if it had it. Mounting something in front of it would require some kind of adapter to clamp around the outside circumference of the port, and while such things exist for other systems, I am entirely unsure whether they will fit this one. As you can see in the tests that I linked, the 10mm focal length is basically unusable behind flat glass - if you want to use the 10-18mm, you must use a dome, whereas the 16-50mm can be used with the separate short macro port and add-on wet lenses. Look at Nauticam port chart for Sony N85 system for examples.
Wet dome or dry dome ?

Yeah that's a problem 
And they don't even sell the 8inch dome directly with the case, all you can buy is case with 6inch dome. I'm starting to regret my old case!
Nauticam is clearly out of my budget at the moment unfortunately...

All packages come with the basic flat port, it is not excluded when you buy a bundle with a dome or macro port.
I referenced Nauticam port chart because it is very informative insofar as how various lenses and ports work together, such as angles of view and working distances. You can consult it and expect similar offers from other manufacturers to work in a similar way.
By the way, regarding the close-ups in the photos that I posted, I have to add that there was a fair bit of cropping involved.
Thanks for clarifying on the cropping!
Yeah that's my problem, I don't need the basic flat port with the 100mm thread. I either need the macro flat port with a 67mm thread (to add my wet dome / diopters and use the 16-50) or the 8inch dome port.

Don't; you'll be artificially limiting yourself, and the old housing does not have a vacuum port, which is an extremely useful feature - I never dive mine without the vacuum valve flashing green. Also, with the old housing, you can only ever use 16-50mm and 30mm macro, nothing else.
Yeah but it's cheap, I regret selling mine for 100 euros (I though I'd never dive again with the a6500)... I honnestly don't feel that worried about the vacuum, I always test to see if there's a leak before I get in the water (and these cameras are resistant, I dropped it a few times in the sea/river (without case), same with my drone, they've always survived ).
Other option is to get the seafrogs with standard + macro port for 447 usd and the 8inch dome for 275 , that's 722 usd! I know it's still 4 times cheaper than other brands, but I'm probably gonna upgrade my camera soon so I don't want to invest too much (but also don't want to go on a dive holiday without anything, or just with a gopro).
I'll try to see if I can find a cheap second hand for the salted line, that would be ideal
