[Seriously Unserious]

I like the idea of a waiting period for the eggs to hatch. We would need a nursery room for this to work best though, but that should be doable. To conserve space I'd rather have it that more then 1 egg can fit per tile in the nursery. When the eggs hatch, we can also have the monster go through a "juvenile" period where it's a smaller version of whatever it's going to be, but can't take any action in the dungeon yet and is helpless until it "grows up." I'd still rather have a list of a few very basic creatures that are created in a simple way as they are now, such as imps and, well, maybe not orcs, but one of the suggested new creatures like goblins or something, as the basic warrior creature that can also help out a bit with the mining. Creating them could then rely on more commonly available resources to create then, say, gold as orcs rely on now.

Relying on gold to create your most basic of warrior creatures has the potential to create some unwinnable maps, especially if the dark mother is surrounded by a large cavern full of hostile mobs and the nearest gold deposits just happen to be inside that cavern. That can create a classic catch-22, you need to break into that cavern to get at the gold to make more orcs to you can break into that cavern to get at the gold.
