Unlikely. Durkon has enough diamond dust for one Resurrection, but he can't resurrect himself. So the dramatically appropriate sequence of events is as follows:
1. Belkar and one other OOTSer are killed (probably Haley, since Roy has been dead already and Elan's death would complicate matters with Tarquin, not to mention make Nale even more insufferable for hours). Presented with a Sophie's Choice, Durkon resurrects the other casualty and fulfills Belkar's prophecy.
2. Later, Malack (also being a Tier 1 caster) fulfills his stated intention to kill Durkon so nobody else can. The Linear Guild is destroyed or nearly so, but Tarquin and Malack are enough to mop up the Oots and signal for backup.
3. Xykon shows up and there's a massive confrontation between him and Tarquin's incoming soldiery, ending in the destruction of Girard's Gate. The last Gate left in the world is in the North, either in or close to Dwarven Lands (and on the other side of several human kingdoms which might be fun to see); the OOTS goes there to secure Kraagor's gate, Xykon follows them, and Durkon has indeed brought doom to the dwarves when he posthumously returns.
The effect would be to make the immediate area photorealistic, and characters would be blinded because they have only dots for eyes and deafened for having ears that aren't drawn large enough to be scientifically capable of gathering sound. Anyone who died, it would be because their existence was a violation of the Square-Cube law and there was insufficient technobabble to explain why their heart hadn't exploded.
