Guys, guys! Shaco isn't completely gutted! I figured out a way to still get double buff + level 3 by about ~2:55ish all solo too. Could probably get it done by about ~2:50ish if you get some help at red.
I run 21/9/0 with AD reds, Armor Yellows, Atks Blues, MS quints. Start Dorans Blade + 1 pot. At level 1 get W.
0:55 - Place 1 Box at Red
~1:10 - Place 1 box on the mushrooms just outside the stone circle by wraiths.
~1:25 - Place 2nd box on mushrooms
~1:40 - Place 3rd box on mushrooms
~1:55 - Start red, place 2nd box, smite asap.
Level Q, Rush your blue afterwards, smite will come back up.
What this does is your 3 boxes at wraiths will kill all the mini-wraiths. The 3 mini-wraiths + both buff camps = level 3. At that point, since more junglers now a day go Buff > Mini > Buff, you meet the enemy jungle at their 2nd buff. You're a level up, double buff (just like pre-patch) and you laugh as you murder them, steal their 2nd buff, troll around in their jungle a bit, gank top, spam laugh, spam dance in turret range for fun, etc etc etc.
