DDJ 1000 + Standalones Audio Out

OK 2 related questions. 

1. Is it possible to connect standalone players to the DDJ 1000 channels 3/4 and use rekordbox performance mode for channels 1/2? 

2. If the above is possible, is it then possible to capture the ASIO digital audio out via USB connected to a streaming/recording pc which also has rekordbox in export mode for the players? Will it capture all 4 channels of audio?

Heres my route... As weird as this sounds.

> DDJ1000 connected to 2 PCs. 
> Standalones connected to outside channels of DDJ1000 act as main decks (I want to get my eyes away from the laptop most of the time) 
> PC 1 will record/capture audio via USB cable AND use rekordbox in export mode
> PC 2 will use rekordbox in performance mode to do extra deck things... Like acapellas/sampler/drops etc stuff thats a small part of my normal workflow.

I cant find solid information on this and would really appreciate some answers as it determines my plan for purchasing the players and whether I need a separate audio interface... 

Thanks in advance :)
