I don't have access to the data files at the moment (no SE4 on this comp), but I am pretty sure that should work. It would be very easy to test.
But, a more interesting system is when some (or all) events and intel projects that do the same things have the same Messages, so you never know if it was intel or an event. Why should you get to know if sabotage blew your ship up? It wouldn't be very good sabotage if you could always find that out.
