88 4.0L Renix to 96 4.0L HO swap...full swap?

Ok so I've searched, read, and researched longer than most do and can't seem to find what I'm looking for. I've got an '88 XJ Limited 4x4 with 4.0L inline 6, AX4 tranny, and NP242 transfer case. Long story short, the head gasket is blown and most likely cracked head. I picked up a '96 complete drivetrain for a pretty good price. The engine wiring harness and ECU are included. I want to do a complete swap to have every benefit from the HO and newer AW4 and NP231. Everything I've read says to use parts from this and the sensors and intake manifold from my 88. But that's not gonna give the full benefits of the I understand it. Is it possible to swap everything into my rig, including wiring harness and ECU? I was also thinking of swap in the dash harness and instrument cluster as well as the TCU from the donor (if it's needed).
Sorry for the long post but I wanted to give as much info as possible. As it stands, my rig has ALOT of upgrades including a brand new TrailMaster 4.5" lift with full leaf springs, 33" Dick Cepek MT, rebuilt Ford 8.8 rear end with 4.10 gear ratio and Limited slip diff, and winch bumper, front and back,just to mention a few. I've also demolished the interior and upgraded to WJ seats. The backs seat and all carpet has been removed to do a custom build for camping/bug out buggy set up. This is my first Jeep and I fell head over heals in love the first time I laid eyes on her. Can anyone help me accomplish my goals or will I be paving new roads for future Jeepers that have an obsession with their XJ?
