Ok here it is how I did it.
First I want to say THANK YOU to DEVILRT. You inspired me to get going on this mod again. I have been working on and off on this for a couple of years now. And I do not intend to Hi-jack your Thread.
You started it. It's yours.
Whoever is thinking about this mod let me warn you it is quite labor intense. It took me sometimes months to rethink and come up with a new idea and some people even may consider it as not save!
You take the newer model Steering Wheel and remove all the parts that are possible.
Cut out the big white connector for the Steering Wheel heating system. You need the space for the 06-10 Steering Wheel (SW) switches. I didn't even consider of connecting it. Who needs Steering Wheel heating on a anyway Hot Car!
Then trim down the outside diameter of the spline on the SW itself until it fits snug in the Clockspring. Install the bolt and you have a first feel how it's going to be like.

You will notice that the new SW doesn't cover up the Clockspring. There is like a 3/8 inch gap between the SW and SW-Column. I did not find anything yet to cover it.

So then the hard part follows as DEVILRT already mentioned. Retrofit the 06-10 SW switches in the bezels of the new SW. Cutting sanding using glue, body-filler do fit checks and the whole bit until you can assemble the SW again and if it is to your liking. Then at the final end paint it or vinyl wrap it.
The SW Harness from the 06-10 SW doesn't need to be modified that much only the Connector to the Horn needs to be replaced. That is the easiest way.
I did the direct wiring Shift Paddle mod with the AMG Paddles years ago. I can't find this Post anymore. I don't even remember if I saw it on LXF or on Custom Magnums Forum. Maybe someone can chime in and provide the link. So I did the same thing with the Paddles from the new SW. I took the Paddles apart and followed the lines on the Printplate to figure which pin to use.
So finally it comes to the Air-Bag.
DEVILRT mentioned that he simply changed the connectors to the Air-Bag. I was to chicken to do it. I was worried if I mix up the wires that the Air-Bag would ignite when I turn on the ignition.
So I simply took the whole thing apart removed the Bag from the new SW and stuffed the 06-10 Air-Bag in the Housing of the new SW.
And this is what some may consider as not save. It's up to you!
I bought a 2012 and a 2006 SW. so I could work on this mod and have one installed in the Car.
You can use the SW's from the 300, Charger, Challenger and even from the Grand Cherokee. They're all the same. I installed an SRT SW from a Challenger in my 2011 Grand Cherokee as well. It was a plug and play mod there.
I'm sorry for the flimsy Write Up. I'm much better in physically doing things like this mod than to write.
