Double Knitting an intarsia/fair isle pattern

Well, the christmas season is upon us, and my social group is doing a Secret Santa thing, and the person that I drew happens to be a World of Warcraft fan. Well, I happened to find an intarsia/fair isle pattern for the Horde faction, and I had the idea that I could do a double knit reversable thing for it, and here is my problem… I can’t quite imagine in my head how this would work :?? I’m new to the whole double knitting thing, and i’m sure it COULD be done, but I would appreciate some pointers and help on this issue ^^
