Animal Husbandry: Or, craft yourself a spawner.

I'm interested in a plug-in that will allow you to create recipes for spawners for specific mobs that can be crafted on a crafting bench.

Specifically, I want these to be a two-stage recipe:
1 ~ Craft a 'blank inactive spawner'
2 ~ Craft a 'mob specific spawner' using a crafted 'blank spawner' and another recipe.
