Add the Ghost executables, and stick different images on the hard disk. Then build yourself some menus (eg batch files) to run the appropriate command lines for the different images you want to deploy.
If you are feeling adventurous, create a GUI menu using an HTA file and then with some WMI code you can auto-detect the machine you are booting from and choose the right image from a look up table.
