There is no way to obtain the functionality you are after. the limitation is caused by the $MFT name tables, and cannot be modified.

The 260 value is MAX_PATH, a Windows architectural limitation, not an NTFS limitation. The NTFS limitation is 255 per folder/directory in the path. The NT kernel limits the total path length to 32,767 characters. – SecurityMatt Feb 17 '13 at 6:39
wrong, you can use "\\?\" prefix to access fully qualified name maximum 32767 characters – Lưu Vĩnh Phúc Sep 13 '14 at 8:04
