I wouldn't reccomend such a system unless your equipment's position is usually temporary. I am myself a learning DJ, and if you have noticed, mixers, vocoders, DSPs etc, are often designed to be screwed into proper mixing desks, or rackmounted, I suggest you build some rackmounting, etc, and maybe a proper fitting in a desk for the mixer - if you're a dance or techno DJ like me, it makes things easier.
However, if you are a hip hop DJ or scratch artist, then it is best not to fit your mixer into the desk, as having the controls for the mixer on the same level as the desk actually helps.
