Minecraft 1.5.2 server with beta 1.7.3 world generation

Would anyone like if a started a survival server in 1.5.2 but had a plugin that will generate the world as it would in beta 1.7.3 for all of you nostalgic minecrafters out there. I have server all ready and everything but right now it is private just for me and my friends to play survival but we are planning on moving our private world to another server and changing this one to a public, beta 1.7.3 world gen, survival server
