I can't think of a way that this would be possible. Some of the fonts are used System-wide, e.g. Marlett, and some are protected by Windows File Protection, e.g. Franklin Gothic.
The '%windir$\fonts' folder is one of the few 'special folders' where the location cannot be changed and I know of no way to add an additional location.
I guess this is because the System File Checker has to complete its checks - particularly of system fonts like Marlett - and a font table created before any profile is loaded.
Hope this helps...
