I dont emagine it would be super tough, rip out all the gutsof the fight stick, remove triggers and anolog sticks from 360 mobo put the mobo in the new fight stick and wire everything accordingly, to just make it work would not be that bad, to make it completly functional will be tough. well to be honest it will all be tough, but it can be done. we canot just tell you exactly how to do it. and i am sure there is no tut for it, you are traveling into uncharted teritory, take lots of good pics as you go along, if you cant get something to work ask and we can help with that function (ie how to wire triggers, how to wire buttons, how to wire stick)
as far as tying the chips together, I am not sure that will work. two problems I see, one is that you only have one stick, the other is that you dont have enough buttons. for street fighter I dont think you need them though.
good luck to you
