not much of luck:

root at ogre2:~# zpool destroy 4146846692207551713
cannot open '4146846692207551713': name must begin with a letter
root at ogre2:~# zpool import -f 4146846692207551713 og
cannot import 'og' as 'og': no such pool or dataset
root at ogre2:~# zpool import -f 4146846692207551713 ogbad
cannot import 'og' as 'ogbad': no such pool or dataset
