Will a Hercules DJ 4 Set, Launchpad Mini, and Traktor DJ software be compatible?

I currently have a Hercules DJ 4 Set. I will be switching shortly from Virtual DJ to Traktor. Mapping is available so I know these 2 are compatible. My 4 Set is very simplistic, so I wanted to get a Novation Launchpad Mini in a month or so. Is this compatible with Traktor? And is there a way for these 3 to work together when I'm DJing? As the 4 Set doesn't have many buttons for live sampling I figured the Launchpad Mini would be perfect. Thanks!
