Release Elements/Themes

Ok so in the case of using a release where it's conceptual, say like a Seraphim... or you use the element holy fire. Is it possible to use both fire and light in that case (more so in the case of the release being based upon a Seraph). For those who don't know a Seraph is basically a rank down from Arch Angels, the word Seraph itself means fiery one, but being as they are angels they would of course be able to use light as well as fire/holy fire. I'm just wondering if the release was based upon the Seraph itself instead of holy fire, is it possible to draw from both light and fire using this release? If not, what's the closest one could get to doing so without overstepping rules?
