On dire side, if you have someone to handle solo lane; Luna is a pritty good option to jungle.
Tried it several times, the only disadvantages are if the enemy knows this trick aswell (very easy to gank or to ward the creep spawn), or if your team is keep dying on any lane and needs your help (which is can't be done since you skill passives firstly).
However, I'm around 900 matches and never seen anyone use this in game except of me and when i used this, the enemy never came to stop me neither. The only true problem was when my team couldn't handle their lane(s) and fed an enemy who easily ganked other lanes aswell while I couldn't help.
But if you play in a party, where your teammates most certainly will be able to do their job, you need only 11-13 minutes to come out with a Lvl 11 Luna with Dominator+Treads.
