I really don't... What year are we talking here? My 4.0 is a 2000, just turned over 112,000 miles, the only things I've had to replace as far as the engine is concerned were an alternator (fried off-roading), and o2 sensors. Oil changes every 3/3000, serpentine belt every other year or so (as needed), air filter when it needs it, spark plugs ever 100,000...
It's running like the day I bought it, turn the key, and it GOES. As far as I've heard, the 4.0s are known for their longevity.

I'd do a little research. Most hardcore dudes when faced with the option stick with the 4.0. Personally, I think there's a cool factor in getting a 6 cyl engine to outperform 350s and V8s. Anyone can plop a 350 into a rig, but how about a kick-ass straight 6!
I'd make a pro con list, and choose that way.
Research what the weight of each engine is. What the cost of installing a new 350 is in terms of time and money.
List as many pros and cons you can think of for each engine.
Think of any other options ie Boring/Stroking the 4.0.
Weigh whether the gains are worth the trouble for all of the scenarios.
Every project is a personal choice, and obviously your resources, knowledge and needs are different than ours.
Are you going to Rock Crawl, trail, pre-run, long distance excursions, haul, etc.

If it runs, use it and abuse it. If it dies, go to the junkyard and get another one. They have to be a dime a dozen.
If you were talking a 350, are you talking carb or EFI. I would take and EFI 4 banger over a carbed 350 any day. Besides, 350 swap in a Cherokee is probably not very easy. I'm sure it has been done quite a bit, but would be a challenge under the cherokee hood.

I love the 4.0, but I love V8s better. I like what you're thinking man... can't beat cubic inches.

Isn't a 350 tight in there?
What about front suspension, would you have to change springs for the heavier motor?

It's a common swap, Ive seen a couple done... there is a guy on here Firemanharry that has put one in his. The downside is you gotta put a transmission in there that will handle the power. I don't think the springs need to be changed, not sure though. Any thoughts Firemanharry?
