Yes please do.
I've found the selection of marine good deck connectors to be particularly grim. I replaced several different connectors with this which as far as I can tell is one of the best options (for some reason I've found 3 threads to post this in today after not having it come up for monthes). It's strong and you can add any type of wire to it later on:
Salty John: Cableport and other fine boat and yacht chandlery products.
That perko connector is decent, I added it for my auto-pilot although I found it maddening that it doesn't have proper polarity protection. You could probably try it but the signal quality would be hard to predict for the reasons you mention.
Besides the other options mentioned I happen to know of this connector although at about $100 for both ends it's complete overkill (assuming you can get it in quantity 1). But the -07 option includes 6 power signals and 50 ohm coax. It's IP-67 and panel mount which could be deck mounted.
