Existence of moduli spaces of pointed and unpointed G-covers

Let AA be a complete discrete valuation ring with algebraically closed residue field, let D=SpecAD=\operatorname{Spec}A, and let GG be a finite group. A GG-cover of DD is the finite cover associated with an étale GG-torsor over the punctured disk DD^*. A pointed GG-cover additionally specifies a connected component. Moduli-space conjecture for G-covers. There exist moduli spaces parameterizing isomorphism classes of pointed and unpointed GG-covers of DD, denoted by GCovPtD\operatorname{GCovPt}D and GCovD\operatorname{GCov}D, respectively. These spaces are intended to provide the parameter spaces used in motivic integration over wild stacks; their precise construction is left open.
