You won't be able to use the [AcceptVerbs] attribute as-is since it's tied to the request's actual HTTP verb. Fortunately the [AcceptVerbs] attribute is very simple; you can see the source for yourself at http://www.codeplex.com/aspnet/SourceControl/changeset/view/21528#266431.

string incomingVerb = controllerContext.HttpContext.Request.Headers["X-HTTP-Method-Override"] ?? controllerContext.HttpContext.Request.Method;
return Verbs.Contains(incomingVerb, StringComparer.OrdinalIgnoreCase);
