Halion 25 hc Question for professionals

Hello Dear Warmane server players. I have a question, I would like to hear the opinion of experts. Is it possible to quickly kill HALion 25 hc using Zerg tactics? All (25) players in the dark, bring the boss to phase 3, lowering its materiality completely to 0% in the dark reality, and then 23 people come out into the light and kill it under bl, using all the protective cooldown for the tank. If this is not possible, please explain what problems the RAID will face in this situation. And another question... Should a meteor fall in the light world in phase 3 if there is no one there?

Thank you in advance for your answers.

I am not a pro, but I can tell you right now, that the tank in the physical realm won't survive the damage, when Halion's corporeality is 70%+ outside.
