No, it would not. You would need a 2wd transmission with a 4x4 transmission mount bolted to it and a new driveshaft.
Whats wrong with the transfer case? Is it really so blown up that you can't open it up, take the chain out, and put it back together?

The '95 FSM has a very detailed description of how to tear down and rebuild the transfer case!!
Here is a write up I did about how to change the input shaft in a transfer case... not exactly what you're looking to do, but it might give you an idea what you're up against. Honestly, it's not hard to do... it's nowhere near as complex as a transmission!

So here is the procedure on how to swap the input shafts. The pictures are of the 231 coming apart, the 242 has slightly different internals, but the same procedure works...
1) Remove the tail shaft housing. There are 3 bolts holding it on, and then hit it with a rubber mallet until it breaks loose.
2) Next, to get the rear bearing retainer off, remove the retaining clip and speed sensor. Then remove the 4 bolts and beat it with a rubber mallet until it slides off.
3) Next, remove the rear cover. There are 3 bolts that are different than the rest. VERY IMPORTANT...MARK WHERE THEY GO!!! The two bolts with the washers are for the guide pins, and right around those there are slots to slide a pry bar under to pry the cover off once unbolted. There is no need to beat it with a rubber mallet.
Once unbolted slide the rear cover off.
4) With the rear cover off, pull the mainshaft and shift rail up and once they are unseated and there is slack in the chain, take the chain off. The pins on the shift fork slide right out of the guide plate on the 231, but require some extra motivation on the 242. (Sorry, I didn't get pictures of this). It should now look like this...
The circled part is high/low range planatary gear assembly. The input shaft is in this.
5) Unbolt the front bearing retainer. There are also prybar slots on this peice, just look around the edge tolocate them.
6) Remove the retaining clip.
With this clip removed, the planatary gear assembly will slide out the back. It should look like this:
7) Remove this retaining clip from the planatary assembly.
The input shaft should slide out.
Here are the input shafts side by side...
Assembly is reverse. Be sure to clean all gasket surfaces and use a 1/8" to 1/4" bead of black or red RTV gasket maker on the rear cover, both bearing retainers, and tailshaft housing. Also make sure the retaining clips didn't get stretched on removal and are seated properly. (One of my clips got messed up). One thing to note, the older transfer cases use a wider input shaft bearing, and I had to put my 231 bearing in the 242 for the 231 input shaft to fit.

You can download the parts manual that has an exploded view of the transfer case. Or you can download the full service manual that has detailed explanation of how to take it apart and rebuild it. 95 318SLT did a good write up on a transfer case swap, in which has pics of all the internals.
