Haven't done it - Have swapped 3.0 to 3.0 but it should work. Intake and MAF are different. I would do the swap and use the 3.0 intake, harness, throttle body, MAF and see how it runs. then I would reflash the DME.
Consider rebuilding your 3.0.. those engines are a dime a dozen now, but won't be in a few years.
