DDJ-wego 2 and ableton live

Hello! 

My software of choice is Ableton Live. Sometimes I need to do some DJ work and I do not want to carry my bulky APC40 controller with me. I am looking for a smaller and lighter controller that I can use in Ableton Live. There are two second-hand controllers I am considering at the moment - Traktor Z1 and DDJ-Wego 2.

Can I map DDJ buttons and knobs in Ableton Live? Can I use it as audio output of Ableton Live? 

Thank you
