No, because we do not currently use the OpenZFS repository directly it
would need to be ported from OpenZFS to illumos.  I would recommend
waiting for it to show up in an OpenZFS release before doing so, as
there can still be incompatible on-disk format changes and bug fixes
after things land in OpenZFS master but before a release.  I would
also recommend coordinating on the illumos lists and/or in #illumos
IRC with other folks that have been porting changes from OpenZFS.


Cheers.
