Sounds like it’s more about aesthetics. If you wanted to make it looks better with SS, You could use a ½” Bar above deck like you have but use much thinner material below, and taper as you go to the waterline.
However, from those pictures that just looks like surface corrosion. The only part I would be worried about is what you can’t see just under the deck. I would think you could clean up the corrosion around the holes with some acid and a bronze wire brush, or SS wire wheel on a small grinder, prime with some zinc chromate and paint again.

The part under the deck is pristine aluminum 1/2” thick. Above deck the aluminum has started to show galvanic corrosion. (See photos). The mast is still off, should I replace, ignore, price out stainless? - if I replace with stainless can I go with thinner plates as 1/2” will weigh close to 100lbs for the piece I’d need and cost a pretty penny. I’d appreciate any and all thoughts or opinions.
