I did not hear about NTFS using >4kB sectors yet but technically
it should work.

The atomic building units (sector size, block size, etc) of NTFS are
entirely parametric. The maximum values could be bigger than the
currently "configured" maximum limits.

At present the limits are set in the BIOS Parameter Block in the NTFS
Boot Sector. This is 2 bytes for the "Bytes Per Sector" and 1 byte for
"Sectors Per Block". So >4kB sector size should work since 1993.

64kB+ sector size could be possible by bootstrapping NTFS drivers
in a different way.
