Not sure if that would come out looking All that well

Look at some of these additives.

I got a new platform from West Coast last year as well and had it sent to Vincent. He had to spray the platform to match the paint on the boat anyway, so he also sprayed on the non-skid and it is awesome... Nothing aftermarket is going to come close to looking as good as this clear non-skid painted right over the paint...

I just finished this one for my boat, I used West Marine Silica in a flour Sifter over a coat of wet Paint. Then another coat of paint to seal it in. I have not had any great success with powdercoat.

ICDEDPPL when I built mine I had it power coated and the powder coater added silica sand to the powder second coat and it worked perfectly .

That's similar to what Baja used on their tubular swim platforms. I'm sure it would work and be the easiest,quickest, lowest price option, except the color contrast wouldn't be the prettiest (available in black also)! But it would solve the problem until you can pull the platform and have it coated.
