Plugin with ya good old squid

I think allot of you know about this but us, me and killerkoda13 had a idea for a new plugin on the server. I know there are a lot of plugins already, but I think this one could be really useful and should really be implemented in Minecraft. The real things the mini mod I thought about was Salvage!! The salvage mini mod takes place in Mcmmo but I thought "why take such a big mini mod when we can make a very own mini plugin only for the server". So how it works is that you would put a Diamond block and a Emerald block place them beside each other and BOOM theres your salvage machine. Your probably asking well what does a salvage machine do?
