That certainly makes it more challenging. Although shelling out to another program that has "AsAdmin" in the manifest file the Windows dialog "Do you want to allow..." will still be shown, and it would need to be clicked before continuing. Something you would like to avoid with a WebApp (Aka pbSilent = True for the framework). Sort of a "Catch 22" as I don't think there's a way around it. Although I would love to be proven wrong!
