You will need a complete donor Cherokee to swap from a 4cyl to a 6cyl. You need the engine, the PCM computer, the AW-4 computer, all the wire harnesses under both the hood and the dashboard, the AW-4 transmission, the transfer case, drive shafts, lots of smaller bits and pieces, etc.
What is it worth to you in time/effort/money ? The most practical solution is to sell the 4cyl and buy a 6 cyl Cherokee.
