Reply to Novation Twitch as FX unit.

Hey guys.
I plan to buy a twodeck controller and remap it and use it like an FX unit.
I play timecoded on cdj's and i have a LPD8 as FX thingy but i feel its a bit small and i stumbled over the Novation Twitch wich brought me the idea of a controller as a dedicated FX unit.

Is there anyone who is familiar with the thought or use the Twitch (or any other controller) as a dedicated FX unit.
I mean, completly remapped, i dont want to use it for mixing, just que juggling, inst. grat. FX, FX knobs, fader fx.

I use Traktor pro 2.5 on a macbook pro.
