No kidding. Playing uneducated armchair quarterback (I am, not you.)
First, make all jeep vehicles with an optional diesel engine. If this presents an emissions problem then create sometype of exhaust filter. If coal plants can create cleaner coal burning, certainly an exhaust filter should not be that difficult.
Next ditch the compass, it is a sales loser. Just produce the Caliber and the Patriot.
Ditch, or combine either the Grand Cherokee and the Commander. Keep one. If you keep the Grand, butch it up a bit, looks like sissified urban grocery getter.
Don't mess with the Patriot or the Wrangler, these are the heart and sales of the brand and will be at the core of its future. I also think the unlimited was long overdue for the wrangler.
Seems odd to have both the Patriot and Liberty, but they both seem to be doing well, so I suppose you could keep them. Personally, I think they should drop both the Nitro and Liberty. There is enough choice between the Patriot and its packages and the Wrangler Unlimited.
Between the Patriot, the liberty, and the unlimited, you get some blurring in utility and practicality. What to do? Definately keep the Patriot, it is capable and fuel efficient. The Liberty adds an off road step up, and don't mess with the unlimited wranger. That is one of the few things done right.
Patriot seems like a good hybrid candidate, but don't know if there is enough room to switch it. The Patriots inards are pretty jammed with technology. So much so my FDII even has a smaller gas tank than the FDI which is small to start with.
Moving on, Dodge, Chrysler, Jeep, need to go even smaller, a sub compact about the size of a Yaris or Aveo and aim for 40 or 50 mpgs or higher. You can add all wheel drive to the Jeep version, but push it as an all/extreme weather commuter. Give it a tiny gas engine, or better a diesel or hybrid, but boost the quality.
I really think that people will buy small fuel efficient cars (as evidenced by foreign cars), but they don't want to be humiliated. Tighten up the interior make make high end audio standard, along with navigational aids, and leather and nice wood as an option even on the dinky cars. I think there is a huge group of folks that would buy a small, fuel efficient, nice car.
What do I know, I have been waiting for a couple decades for someone with half a brain to build the Patriot. I think we see the logic in this reflected in positive sales with zippo advertising.
The patriot isn't huge, but it feels huge to me, it is massive compared to my neon, but when one stops to think when driving their pat that this is the smallest vehicle that is generally available from Chrysler/Dodge/Jeep that just doesn't add up. Wrong direction. More like missing a 3rd of the equation.
