Another store called WolfsWorlds has a Tosche station set that you can just order the accessories from and it has a bunch of nick nacks. I would link it but 4chan thinks it's spam.
Beskar ingots are pretty easy to make at that scale. I would just get some .040 styrene strips, cut a bunch of pieces, and paint them silver.
