Reply to xone 2d & traktor X1

i've been on traktor with an audio 4 dj and x1 for the last year or so. have vinyl control but never use it when i dj out. (only at home). when i play out i'm plugging two line outs from the audio 4 into an external mixer and controlling with the X1.

i play a lot of music that drifts so a jog wheel and a slider assigned to pitch control would be really nice.
i am believeing of picking up a xone 2d. can i use the x1 and the xone 2d at the same time?

i have done a couple of google searches and haven't heard of anyone using both.
is this possible or are they basically redundant functionally?

i don't love the audio 4 and i would prefer to go to the all in one of the xone. but i love my X1 too.

anyone out there a few steps ahead of me on this one?
