It can, and has been done, however I can almost guarantee that you don't need it. We already have an 8.8" diff (at least in the V8s and SCs), and there are a number of people who have made low 10s passes on the stock IRS. The only ones that have problems are the people running a manual trans with ridiculous power levels, and launching on slicks. Other than that, the IRS will handle quite a bit of power before it becomes a limitation.
