Simple Spawner Stacking plugin

Plugin category: Essential

Minecraft version: Spigot 1.8.8

Suggested name: SpawnerStacker

What I want: Just a plugin that allows the player to stack spawners. Most of my players have a stack+ of spawners and its easier to be able to stack them when building so you don't need as much room in your grinder. I have SilkSpawners and MobStacker so I would like it to be compatible with those if it's not too hard.
Maybe add a config file where you can edit the max amount of spawners that can be stacked on each other so its not too over powered.

Ideas for commands: /spawnerstacker reload

Ideas for permissions: default players are able to stack spawners

When I'd like it by: As soon as possible

Can you stack different spawner types?

 

I think that would also be a little overpowered, just mob specific. For example if you place a pig spawner you can place x amount of pig spawners inside that spawner.
