Rekordbox DJ with 900NXS2 and DDJ SP1?

I currently have a DDJ-RZ, but miss having a 'proper' mixer to hook my 1210s into.  I can't afford to buy the mixer and 2 x players in one hit, so was wondering if I could use rekordbox dj with just a 900NXS2 and a DDJ SP1?  This would tide me over for a few months until I have the cash to invest in two XDJ1000Mk2s...

Thanks in advance   : )
