I don't think I understand your scenario here. The docs online at <http://docs.sun.com/app/docs/doc/819-5461/gazgd?a=view> describe uses of zpool replace that DO run the array degraded for a while, and don't seem to mention any other. Could you be more detailed?
If a disk has failed, then it makes sense to physically remove the old disk, insert a new one, and do 'zpool replace tank c1t1d0'. However if the disk has not failed, then you can install a new disk in another location and use the two argument form of replace like 'zpool replace tank c1t1d0 c1t1d7'. If I understand things correctly, this allows you to replace one good disk with another without risking the data in your pool.
