I think everyone will agree the Compass should be the first to go. Take the Compass tooling and make a replacement for the PT if you need to do something w/ the tooling. Next in line is the Aspen/Durango. Neither are doing well and both are not only low in their class rankings but horrible in the gas mileage department. Take the Commander chassis and redo it to a decent looking large/midsize 7 seat Durango and make an on road sport tuned version of the Grand Cherokee for Chrysler. The Patriot is exactly what it should be, only get rid of the FWD model and make it awd/4wd only. The Liberty/Nitro are OK but I would like to see a pickup version to replace the Dakota (something like the M80 concept would do great). The Avenger needs a different name and look. The styling would have made a great Charger update but do you really need a mini-me Charger? The Sebring actually just needs a restyle on the C pillar and rear end (though I haven't seen the interior in person to know how that part looks). The Caliber is doing very well and remember it isn't replacing the Neon, that replacement is still coming.
What I see that Chrysler doesn't have that it will need, should it want to be taken seriously as a luxury brand and a world class car maker, is a compact RWD sports chassis. A Phoenix V6/Hemi V8 powered balanced RWD sedan/coupe/vert could definitely bring credit to the company.
