Hmm... I don't think it will work.
I made a lot of changes from AoD to AoD2, you can read them here:
The biggest change is reducing the max HP from 8 to 6, and this one change really effects a lot of things in the game. For example, to learn from the Master in Swamp of Talis, now you need 2 cards, not 3 cards.
Other than that, each card is revisited and I changed almost all cards I think, minor or major.
While the overall feel (AoD and AoD2) is almost the same, IMHO AoD2 is an improvement from AoD, and with the stretch goals: more replayability ;)
