It will work, yes. But AFAIK, it's not common practice - it is used but IMO, you should try to stay as non-interfering as possible with SA-MP callbacks. If it's that important, you can just use your own callback. If the problem is copying code over two times to two different callbacks, then the code is the problem - it should have been a function.
