The switch is probably bad. My '91 has a bad switch, I'm not sure if they make new ones but you could just wire in a flip switch or something.

It's a gravity switch on the socket. When you lift the hood, a bearing rolls back and makes contact to complete the circuit. When you close the hood, it rolls forward. It's a very common failure on older vehicles, but it's generally cheap to replace

I've never seen a non-gravity activated underhood light on a Cherokee. I don't know for certain if they use mercury or a ball bearing for contact (or possibly what year they switched between the two), but I haven't seen an OEM light with a separate switch.
As for the second picture, I'm not sure what/where that is

The second pic is up by the battery with one tang coming off it. Its a plunger type switch I think, I'm just not sure what its for.

Even at $10/gal it will take an EXTREMELY long time to break even on the parts and labour. To swap a 4WD XJ to 2WD with decent used parts could be $100 if they're being thrown out or $2000 to buy, and at the minimum will take you several days, plus related consumables and hardware. For about 1 MPG average increase... maybe. How long do you plan on keeping the vehicle? It's a pretty bad ROI. Cheaper would be to find someone with a 2WD XJ and offer them a straight trade.
You don't need to 2WD swap. Remove the inner axle shafts and front drive shaft and you have a 2WD vehicle that just weighs a little bit extra.
However your best bet is to look into LPG like you said. Guys in the UK love those setups. FAR better return than spending thousands of dollars to eliminate 100 pounds of weight.
