11th gen XRS is pretty unlikely just because Toyota tested the XRS with the 9th gen and 10th gen and it was just too much to make them vs how much were in demand. Although, Toyota could still randomly bring a more sporty model for the Corolla especially since they were saying that TRD versions of the Corolla and Camry were in their minds. As for swapping the 2.4L in, the engine should fit as well as the transmission nut the wiring will be different. It's possible but I say if you're going to do a swap that big, you might as well go for the 2.5L 2AR-FE with a 6 speed manual instead of the 2.4L 2AZ-FE. It's the newer version of that engine and it fixed the oil burning issues that the 2.4 had.
