Yes, that will work. The only requirement is that you cannot home more than one axis at a time (EMC won't know which one hit the switch). The ini file parameter HOME_SEQUENCE will let you enforce the "one axis at a time" part - check the manual for details on how to use it. The other limitation is that after each axis homes, it needs to move off the switch before you can home any other axis. If you are using the same switches for limits, you've probably already taken care of that.
