I know if I found one close I could get it to work. How do they mount to the housing?
The problem you would run into is the same one I ran into trying to adapt to my Ikelite housing, Inon makes a plethora of different housing specific adapters but there are very few pictures or specs on them to choose the one that might be best for modifying--lol--and--they make none specific to your housing
Your other direction would be to adapt a step up ring so that you could use the threaded type WA lenses from various manufactures, most less expenisve than the high quality Inon stuff. it does not appear your housing has any threads, I wonder if it might be possible to either cut threads or bond a thread ring to the port to accept a step up ring to 67MM.
