If you will notice most variable vane turbos (aside from very few truck applications) do not use a twin-scroll design for several reasons. The main idea behind a twin-scroll conventional turbo is to create a more efficient and more ideal flow scenario for the turbine. This is accomplished on a much greater level with variable vanes which create ideal turbine flow geometry at any given rpm.
