Yes; just note that with a 1k blocksize, 2^32 blocks will only get you
as far as 4TB, not 16TB.  But yes, it should work.

However, 1k blocksize is usually a bad idea unless you really need the
very very best space efficiency on the filesystem: it usually performs
worse than 4k blocksize, and it imposes other limits such as a maximum
file size of a bit over 16GB.  With 4k blocksize, a 3.27TB filesystem
should just work.
