Thinking about deleting all that junk. Pros and cons of all. Just want to make room for some storage...
Thinking about deleting the smog system

Dont do it. I wish I had kept the many smog pumps and parts off the various vehicles Ive had over the decades. They would be like gold now. Secondly If you think its gonna make your jeep run better,think again. removing the cat will do nothing but asphyxiate you when the top is off or the back window is rolled up if you have a softop. Screwing with any of the sensors will keep in open loop and run like chit. Just leave the emissions alone and move on.
How much storage room do you think you are going to gain by removing your smog components?
My smog system isn't behind my rear seat. 
Maybe I'd better look again, so I can fit more tools in my Jeep.

That type of mindset is outdated many years now..there are reasons for emissions stuff on our jeeps and removing then will do nothing but cause issues.
I'm still trying to figure out what smog equipment we're talking about and what else I would store there. Behind the passenger rear fender and next to the transfer case just don't seem like convenient places to use for "storage".
It's not like there's an egr and smog pump cluttering up the engine bay or something.

My 2002 has its evap system on the drivers fender and takes up a lot of room
Maybe he has a 4cyl because on mine the smog stuff is in the engine bay not the rear. But still if you remove that not much you can put in it's place other than maybe an air compressor.

And it will continue to set a SES light every time the vehicle’s PCM meets parameters for performing EVAP tests.
You will set codes for large and small evap leak, leak detection pump, etc.
The only way to prevent this would be to have a someone with the skills to shut off all the evap system in the PCM, and there is no one that I know of that would do it, including @Wranglerfix .
I gotta ask - would you please explain this one?
I would never jeopardize my reputation and company by doing this.
Are you looking for those crazy MPGs?
What else do you need to put there that can't go some place else?
Crazy for me would be double digits!Are you looking for those crazy MPGs?
Nothing really,maybe a toolbox or something.I just had a code from it,redid a few of the soft hoses codes gone now,it was the 90degree going to the vacuum check pump
There's lots of room for storage between the front tires if you take the motor out.
I had a friend who had an FJ 40 with smog pump inop and he could not get it registered in Colorado. In TX it does not matter after 22 years. You might want to consider the ramifications of your actions.
