It's really not practical to add a filter to the WWL, there is no m67 thread on the 1-b so you would need to install on your port and burp it - potentially it may vignette a little losing some field of view depending on the application.  The filter would need a front thread to take the Nauticam bayonet adapter.

keldan also manufactures spectrum filter for wwl1 lens without a thread https://keldanlights.com/products/filters/filters-for-cameras/spectrum-filter-sf-2-wwl-1.html

I'd ask for specific experience with this filter, you need to ensure that air bubbles are removed from the filter or they'll ruin your shots.  I wouldn't like to try to install that filter underwater.
