You could talk to the guy on the site and ask him about the bell housing adapter and clutch set up that he done.

of the 2 engines the 4jb1 might even do better than 8 in a cherokee the 4jg2 will be around 9 or slightly over. In my bighorn which is pushing 4000 pounds and a more shed like in shape will do 8.3 l/100km at an average speed of 100kph but that is on a manual trans. Both engines are available with the auto trans and looking at my book it should have a separate bellhousing. If this is the case then taking the isuzu bellhousing and bolting it to your auto will save a lot of headaches.
The 4jb1 was sold in the utes in some markets up to about 98 so a later motor should be available but how to verify the year of the engine I dont know. Licensed copies of this engine are still made in China and Brazil.
Another option is the 4ja1 engine This is only 2.5l but much the same horsepower and similar economy to the 4jb1 It was also sold in USA in some vehicles. It was a new engine in the late 90s so it must meet the rules

It seems quiet common in phillipines using 4jb1t and AX15 transmission together to repower cherokees over there.

The petrol jeeps over here average 17mpg or about 16l/100km
Even with Americam gas prices thats lots more than 20 bucks a tank

The wizard is 7 years younger and far nicer to drive but the difference means getting 600km to 700km to a tank instead of 700 to 900km in the Bighorn. The auto and extra weight pretty much eats all the power difference although the 4jb1 is running extra boost. The bighorn is noisy due to no carpets and has all the wrinkles you would expect from being used offroad for 16 years. Its no longer a pretty car
