I haven't seen this done before.
You know the DCT shaft is shorter, so of course the 6MT shaft won't fit. You'll also need a new diff, console/shifter, etc. This is a very complicated job, are you sure you're ready for it? Unless your car had a transmission failure and needs a lot of refreshing anyway, it would be far simpler and cheaper to just sell a 6MT car and buy a comparable DCT car.
