34t cw will have a 2.7" radius, so you can measure back from the center of the bb axle about 6mm out from the edge of the bb shell and see how much clearance you have from the chainstay at that distance. Remember that riding torque will cause the cw to deflect a little side to side. It is likely to be close as ATB frames assume small cws. The 50t cw has a 4" radius and is going to be about 12mm from the edge of the bb shell. OTOH if you just use your triple length axle it will clear ok. You will have to raise the FD up a bit.
Edit: assumption you were going to shorten your axle to double length. Steve
