It's not clear that there's a metaphysics and epistemology of modality that can vindicate a cogent modal ontological argument for classical theism. Theistic activism and theistic conceptualism with respect to possible worlds are a bad fit with the modal ontological argument (circularity). But so is Platonism about possible worlds (runs afoul of the aseity-sovereignty doctrine). Perhaps a dispositionalist/powers-based account of modality is compatible with the modal ontological argument, but prima facie, dispositionalism entails moderate modal skepticism (cf. Jacobs, Vetter), thereby undermining the possibility premise in the modal ontological argument. What's left? Modal fictionalism? That's already been shown to imply devastating problems for the modal ontological argument.
Upshot: Cogent modal ontological arguments (at least ones friendly to classical theism) seem to have no suitable home in the metaphysics and epistemology of modality.
