SYE alone will not be enough - you would also need adj UCAs in the rear to bring diff pinion in line with TC output. Implied is a new double-cardan drive$haft.
UCF "no lift TT": The angles are close to the same as an OME spring lift IIRC. U joint angles stay under 10 deg. Some jeeps are more sensitive to imbalance in U joint angles than others. The TC end tends to have a steeper angle than the diff end... thus the potential mitigation via MML.
Keep in mind that 7 deg at both ends will be smoother than 5 at one end 10 at the other even though the net lift may be the same.
Another caveat: if you do decide to go UCF + MML you will potentially run into exhaust contact on the pass side UCA mount. I recommend dropping your exhaust center piece (the piece with the cats welded into it) and cold working (read hammering) a dimple or crease in the area of the UCA mount for clearance. don't worry about exhaust restriction - a little dimple is not going to significantly impact flow despite what some web wheelers would have you beleive. You can also push your motor over as much as possible at the pass side slotted bolt hole on the motor mount but on some jeeps that is not enough. YMMV.
