Anything is possible with the right amount of time and money. Without testing two identical turbo, one with single scroll and the other with twin scroll housing on this platform in the same location, it's hard to speculate. Unless you're trying to spool a GT35 or larger turbo with a T4 twin scroll housing and dual WG, we don't feel the gains if any will be noticeable on a smaller frame turbo like GT28 or GT30 to offset the extra work. plus you'll have to make sure your runners are merge to the correct collectors on your header.
