Reply to Need advisory Diy MIDI FIGHTER+CROSS FADE

hello everybody,
i need advisory before believeing about my midi controller. I want to do a model like the midi fighter with the 2 faders and 16 bouton but i want to add a GOOD cross fader (for scratchin).
i don't know if it's realisable (with inno bender or innofader by example). I want to know this before beginning my reflexion process and preparation.
