DJM-750 for 2 XDJ-700s & 2 Non-Pioneer Decks in Rekordbox DJ

Would using the DJM-750 for two of my XDJ-700s (HID mode) and Numark two of NDX400s (using timecoded CD) work properly?

Guessing so, upon purchase/subscription of rekordbox DJ/DVS?

I want to use Rekordbox DJ and have all 4 decks use-able to mix tunes on.
