2. My union mates #1 and #2 joined.
3. #2 did a single nuke, then #1 finished off the rest of the rage bar with abi only.
4. I attacked. The Rage Trigger proc'd. So your theory (and mine too) is NG.
5. Next step, #1 attacked. Rage Trigger proc'd. Joining and then stunning with abi before moving is also NG.
6. Last step, #2 attacked. Rage Trigger did not proc.
Basing on this test run, it would seem that if you are not the one responsible for pushing the boss into mode change, it will not trigger the attack. ...At least this is what we thought. Later that day, Shade (or was it Blubbergott?) tested out our theory too. He repeated Union Mate #2's step, but the Rage Trigger proc'd. We raised the white flag from there. The only REAL way to skip it, is to force her to skip her turn using para or charm.
In the end, I think it's best that, whenever you see the boss in rage mode and not immobilized, just assume the worst and brace yourself for the Rage Trigger. OR, Just bring dispel.
