Having read over the differences between the previous edition and this "revised" one, I think most of the changes are just rules.
The only thing a conversion kit would have to offer is the new combat system cards and a bunch of "search tokens" for the new searching mechanics.
I can find (or make) search tokens easily enough myself, and as for combat, I've already found a dice variant I'm happy with.
The thing about card-based combat systems is they're slower than dice. They add an element of strategy because you can pick your card and maintain a certain level of control, but they invariably slow the game down in the process. Because you have to think about what card to play and then play it.
That's all well and good if the game engine as a whole is fitting of such strategic decisions, but DungeoQuest is easily one of the most fast-paced, randomly chaotic games I've ever seen (and that's what I love about it.) I don't see the point in having a long thoughtful battle against a menacing skeleton if I'm going to be auto-killed by a swinging blade in the next room. DQ is the perfect example of a game that was made for dice-based combat. Fast, random, unpredictable, and deadly.
When I heard the revised edition had a new combat mechanic that "harkened back" to the original 80's game, I was really hoping that meant dice. But as it's still cards, I'm not too interested in converting to that system anyway.
