I'm sorry I vanished for two months. Little Oddom is still resting happily in her cell, so far as I'm aware. Nothing interesting ever really happens at Valefortress. I'll get back to testing Oddom as soon as possible. I'd nearly forgotten about my plans for her.
On another note entirely, vampirization hasn't yet been considered as a factor in supersoldier creation. I have no idea why. It instantly generates the requisite massive strength and dexterity, which makes it the most efficient way to achieve superdwarvely status. It is necessary to clear the [NO_DRINK] tag to avoid sobriety issues, but that's a simple modding job and (I'd argue) it's more realistic than the alternative.
Tragedy training can be accelerated by providing a visible dropzone to execute goblin captives. Wild animal training would make much more sense under those circumstances because it would provide more rapid combat skill training, which is the only remaining relevant characteristic. Twelve years of this and we'd have vampire child supersoldiers worthy of any battlefield, without any significant exploitation or modding to invalidate the results.
Lastly, I should mention that things are going to change a lot with the next release. Unless Toady gives us an easy way to have smooth walls, feeding the food stockpiles of daycare children will be quite difficult without inadvertently allowing their release. Further, mental attributes are getting a lot more complex. A lot of research will need to be redone.
