One simple workaround would be to maintain three files and to copy 
the relevant actual file - file_1 or file_2 - to another file called 
header_file. You could create a script or scripts to do this and 
possibly associate them with icons, which would make performing the 
chosen copy action either a simple command or the clicking of the 
appropriate icon. Lilypond would always use header_file, but its 
contents would depend on which of file_1 or file_2 was most recently 
copied to it.

I trust this helps.
