I think the last line would fail to build since snd_timer_user_status64() is defined 'static' in a different file.
Also, snd_timer_user_status_compat() seems to be the same as snd_timer_user_status32(), so I think you can redirect it the same way as snd_timer_user_status64 after making both functions globally visible.
