With the Magnum line, Chrysler standardized the parts, so the engines have the same induction, heads, and exhaust. The 5.2 has a higher lift (better) cam than the 5.9, so no need there. Keeping the 360 computer isn't an issue. As long as you swap from the same group, meaning OBD I or OBD II the connectors and harness will fit. Same water pump and other bolt-ons. Remember that the 5.2 is a zero balance engine, meaning there is no external balance weight so you'll need to knock the weight off your 5.9 flexplate, or use a flexplate for an OBD II 5.2 ('96 and up). I'm thinking you'll need the 5.2 harmonic damper also.
