Will a 93' 4.0 be a direct swap with a 96' 4.0?

Yes, but you will need to swap the intake and maybe the oil pan and oil pickup(2x4 or 4x4).
Could just be the upper intake you will have to look, '96 had the IAT(intake air temp) sensor built into the MAF sensor(6 wire), your '94 has the IAT on the upper intake and a 4 wire MAF.
The '96 will have a CPS(cam position sensor) and syncro shaft(oil pump drive), your '93 computer/wiring won't have that so you will need to swap your Oil Pump drive gear into the '96, it is just under a cover plate behind lower intake manifold.
You could just leave it but...............these syncro shafts had problems with bushings wearing out.
With engine out I would replace the rear and front main seals, they are inexpensive and a pain to do with engine in the vehicle.
Also I think Ford made a change in the crankshaft to flywheel/flexplate mounting between those years, but part numbers shows them to be the same, so just a heads up.
