(That is my Gneiss up there from Soom, her sculpt is one of the "recast" examples in the article).
The goofy part about doing that is that the porcelain world overlaps the bjd world, so recasts are easily spotted--and porcelain needs different shapes than resin to be sturdy. Also the aesthetic is just different IMO. But it's something to watch out for as porcelains are so fiercely expensive (which is why I don't have any).
Thanks to Cat for finding the article!
