Map Generation

I was debating between posting this in Plugin Requests or here but thought maybe this would just be a good place to start.

Anywho, I am working on a new server idea based around RPG play and such. I have let some people play and build while setting up the server over the last few days, but now have realized this has kinda put me in a tough spot.

I need to create a new world, but I want the world to be the exact same that it is right now, down to every hill and cave. I also want there to be no ore of any type, diamonds, coal none of it. Everything else the same though like trees, stone and beaches that kind of stuff untouched, just all ore materials replaced with stone or something.

I was wondering if this would be possible? I have tried taking a look at custom generators and they all seem to alter how the land actually looks or how biomes are spawned. I still want the same world just no ore. Anyone have any ideas on if there is anything out there that does this?

Thanks in advanced.

 

Why not go through the world with WorldEdit and replace all the ores to stone?

Or perhaps go with MCEdit.

That was one of the options I thought about, but a lot of world has been generated already unfortunately, it would take forever.

Most of the players have agreed to resetting the world if I copy paste their stuff over. So really all I need now is a world generator that stops ore from generating, the map doesn't need to be the same anymore. Anyone know of a world generator that still keeps some what vanilla generation but without ore?
