I've come up with a SoC variant that combines some of the better elements of the SoC card game with the original game.
I use a Deck of Dice with 40 cards. The 36 from the standard Deck of Dice, 2 reshuffle cards, and 2 event cards.
The event cards are comparable to rolling a ? in the card game. There is an event deck, and the player who gets an event card in the dice deck draws a card from the event deck. The event deck includes things like:
productive year, every player gets a resource of their choice
drawing player gets one development card
locusts; all grain in player's hands is lost
civil war: all harbors are useless until a player draws a 7 as their normal "roll"
Basically, most of the event cards from the card game can be ported to the board game, and I have ideas for some more cards.

I don't think there is much chance of publishing it. Since Mayfair makes SoC, the SoC card game, and the deck of dice (at least in the US), they'd probably object to anyone else publishing what I'm describing. They also aren't exactly the easiest company for an unknown deisgner to approach.
I'd consider making PDF's available but even that might get me sued.
