In my experience it will break at some time if you try to "hack" the metadata of eclipse.

Consider the substcommand in windows (As you mention drive letter I assume windows)

To remove the mount do

subst /D N:

You might consider making a bat file that mount N:, start eclipse and after eclipse exit unmount N: something like

startMyProject.bat:

subst N: .
N:/eclipse 
subst /D N:
