Nikon 24-50 and WWL-C

Hi! I pop up here every 6-12 months or so. This time I'm thinking about the Nauticam WWL-C.

Currently I dive with a Nikon Z7 in a Sea&Sea housing. I also own (among other things) the 24-50/4-6.3 and a Z8.

I understand that the 24-50 and a WWL-C may take care of very much of one's non-fisheye wideangle photography, and in a convenient package.

Question 1: Can you use the lens more or less wide open with good image quality?

One thing I like with my 14-30 + Sea&Sea correction lens behind a large dome is that I can get decent corner results even at fairly large apertures. Would like to do that with a potential 24-50 + WWL-C setup also.

Question 2: Is there a good way to use the 24-50 with a Sea&Sea housing? It's not in their port chart. And, provided you can, is it possible to use it with the WWL-C and get good results?

The brute force solution is to switch to Nauticam equipment for my Z8 but that's quite the budget undertaking.
