I’m presonally against recanonizing the inorganic shapes for the Inika mainly because Greg has been adament enough about them being the same as the organic ones, just not organic ya know.
I’m also not super fond of regional variants as they are really not necessary. However if a 3d print Sanok that has a different shape from the one released by LEGO then having it be a regional variant or a new mask is the way to go.
on the same but slightly different note, I wouldn’t mind the Suletu having its design sligthly altered for its inorganic mask as it has plenty of grey area surrounding it but I would like the mask to still be asymmetrical like the original Suletu piece even hints at. I’ll have to make a 3d model of that sometime…
