ah but that would stop oro from using the sharingan as a major weapon because he wouldnt have access to the mangekyou (sp?) as was previously stated the user must have full uchiha blood, so whether an offspring from sasukes body could use it is debatable because it wouldnt be full uchiha, the best way would be to try to clone sasukes body, or who knows he might find a better vessel in the next 50 years
