God no. The current elemental resistances of SAN are, as the name says, "elemental resistances", the mostly "physical" elements that you get buffeted with head on through most magics, which go directly against how well your body can resist it.

Some elements are intentionally rare to have any form of resistance to. Acid and Sound in particular require specific gear, rather than the power of a god/purity of soul, being elements that affect through matter itself to a molecular level if we're being nerdy about it.

It makes sense the way it is. At least in my eyes.
