I'd be super careful with it but as long as you and your DM don't mind go for it. Obviously several folks here have pointed out some sweet combos that show not all subclass abilities are balanced by level. Although I have to say I really never got why Burglars were able to Use Magic Device and not Tricksters. Still, my halfling burglar Dual Wielding his Holy Sword and Staff of the Magi talismans of both good and evil around his neck is truly worthy of gracing the cover of this month's issue of "Metal as F*&k" magazine. And yes, that is a Dwarvern Thrower sticking out of this back pocket, because this Bilbo is Metal as F*&k.
