Yes, it is possible and has already been done by many Skoda (and other VAG cars) owners on their own.
The possibility of retrofitting and, accordingly, its cost may vary depending on the basic configuration of your car, the availability of VCDS and / or PagCanPRO (VCP), etc. and work skills. I myself am now in the progress of retrofitting my OCTAVIA. For more details, I can recommend to visit www.drive2.com. Unfortunately, the most of upgrading projects are written in Russia, but several ones can be found in English.
I'm also sure that you can find many people or firms near by that are specialized in such retrofit. Good Luck!
