Given any "swap(exp, new)" function can be implemented as "exchange(exp, new) == exp" I'm not sure why we have two complete sets of functions all the way through. But I guess that is a different issue. :) Yes, it might be possible after some careful performance analysis (we might run into some subtle issues).
They don't quite generate the same code, and there is no way to write an "Exchange" version of a weak "Swap".
