Here are two old DP hacks, translated in french
Danger & Dragons: http://www.mediafire.com/view/kn6ayno6vw09zwl/Danger_and_dragons_VF_01.pdf
Legend of Fallenthrone: http://www.sentientgames.com/downloads/lof.pdf
Personnally, i feel like DP is a kind of (even) more cinematic kind of version of Btid. And i'd love to see a more "complete" (ie: not only fights) version of DP, borrowing from bitd.
regarding your hack, i think you should ask directly to J. Harper.
