Reply to Producer goes DJ, gear decision

Hi!
I've been produced stuff for years, and now I need to create a simple laptop-based Dj-setup and perform under my project's name. The important thing here: I want to use only midi devices. DAW - Ableton Suite.
It's going to be a two-person(!) Dj-set.
So, we are already have some gear in the studio:
- TC Electronic Impact Twin
- Novation SL MKII 49(going to use it for synth-lines also)
- AKAI APC20(for cliplaunch mainly)
- Novation Launchpad(maybe for FX?)
And I'm going to buy Novation Nocturn and use like a mixer (eq+crossfade)

Any suggestions?
Btw, sorry for terrible English and thanks in advance
