I believe there may be a couple of things easy to miss:

1) did you bring over the non-default ("local") attributes of the zpool, including 'bootfs' and perhaps 'failmode'?

2) how is the 'npool' ultimately called and how is a bootfs referenced in the new copy of the grub menu (still 'rpool'?)
Note that to rename the rootpool you might use a live media and zpool import-export trick, with a renaming import.

3) is the rootfs and dataset hierarchy leading to it compressed in a way grub can't read (i.e. gzip)? I believe it only permits uncompressed and lz4...
