The RPG market is hard to break into. I've ported quite a few creatures from Domions to the old DragonQuest RPG system with permission from IW, but it was a fairly easy task to do given the mechanics of the DQ system (the magic doesn't translate too well).

The thing is that any effort of that kind would require a lot more material than is available now in the game descriptions, it would need to be molded into a suitable format, thoroughly proofread several times and checked for consistency so that the continuity doesn't piss all over itself. It would, from certain perspectives, also have the not so minor problem of locking things in stone so that it would be much harder to change things later even if necessary. It also requires a lot of work of a different sort, which would make it a multiperson project and the question of who IW would be comfortable enough with to have lend a hand would not necessarily be easily solved.
