it won't work for long.
the heat from brazing it, or the vibration of the motor, or both, will work harden it and it will crack at some in-opportune moment... could cook your motor, if not worse.
sry guys, I just dialed in, and saw this... had to put in my two cents to save you some grief.
I'm using Silver Solder and if I remember right the only way to work harden copper is pound on it or bend it. The heat used to Silver Solder it will anneal the copper if I'm not wrong.
How would you do this if you had to make an intake then?
