I hope you have winter tires for this. The Alps, in winter are not kind to a powerful car with temperature hardened grip-less summer tires...

Here's a nice graphic where you can see how the spline'd sleeve would work.
it would be a cup or ring with two steps of different diameter splines, the outer step locks to the red output shaft and the inner to the purple "return" shaft. I think you could do it without stripping anything in the main gearbox case, just the centre diff section.
You may even be able to do it by simply pinning the two concentric sleeves (black in the pic) in the standard centre diff together.

Sorry... See my next post..
Discussed previously and decided against this option because of cost.. But now increasingly reconsidering

I dropped the car off today with Tom. I'll keep the thread updated as he goes. I've considered colour options and I think the most likely right now is Oslo Blue.. Tom is going to paint up a door he has lying around so I can judge it properly but a few pics below..

I am not even talking about going forward, which I agree is doable (if not ideal) with summer tires on a C4, but rather stopping, where 4WD or not, summer tires are worthless.
Here in beautiful Switzerland, you crash in winter with summer tires, the insurance wont't cover you, arguing negligence on your part.

Tom has sent over some pics of different Oslo's.. current preference is for the darker older shade..althought the other is not bad too.. amazing how much they change according to light..

I like the cobalt 
hey you'll need to change the name of the project - what's the atomic number of Oslo?
TBH either of those two Oslo's will look pretty cool, I'd prefer the lighter of the two I think.
