I don't think hypersonic missile interception is possible, unless the US gets laser weapons working or something like that. Hypersonics are incredibly fast, and Russia's fighter jet launched hypersonics easily defeated the Patriot air defense systems in Ukraine, when they targeted them. Even intercepting normal supersonic and subsonic cruise missiles is a crapshoot, the iron Dome in Israel gets defeated by homemade rockets at times. Interception technology is very overrated currently.
