With the Cummins powered Rams they solved it by using variable vanes.
That works well, but doesn't sound as impressive as twin turbos. Then again, most claim that their Cummins has an intercooler, which sounds better than the charge air cooler it actually is.
Somewhat like that there are now 4-door SUVs called coupes, because the rear window slopes more. It doesn't have to be factual, just sound good.
