400 gal and multiple tangs........Mission Impossible?

[D0661E750]

I'll keep this short guys. I am aware of the aggression so I would like to add the fish all at the same time, please advise if there is any other way that could make this right or a smooth as possible. Need your expertise and experience. I will use mirror technique, dark mode for a few dayz, and will feed them 4-5x a day.

Currently in DT:

• Hippo- L (5-6")
• Sailfin- ML(4-5")
• Yellow- M (3"), shy and gets bullied by Hippo and Sailfin
• 3 small damsels
• Coral beauty- S (2")

Holding Tank - Sump (4 stages)
1st stage: no fish
2nd stage:
Desjardini- L(5")
Emperor Angel- L(5")
Powder Blue- M(4")
Yellow- M(4")

3rd stage:

• Yellow Eye Kole M(4")
• Powder Brown- M (3")
• Juvenile Koran Angel- S(2-3")
• Niger Trigger- S (1- 1.5")
• Percula Clown- S (2")

4th stage:

• Orange Shoulder juve- M (3")
• Pair of Clarkii town (2" and 3")

Quarantine Tank:

• Gem Tang- L (4"-5")
• Sohal-L (5")
• Achilles juvenile -(3")--mean little guy, no fear with Sohal
• Purple Tang juvenile (2")--mean little guy, no fear with Sohal

10gal sump:

• 4 babies percula clown (1.5")

20gal QT:

• Blonde- M (4-5")
• Clown M (4-5")

Strategy: Capture the tangs from DT then place them in the sump. Once all settled, I will add all the fish in the DT at the same time.

Mixed thoughts here, should I add the small tangs like the Juve Purple tang and Achilles first?

Another reefer is also selling me his 4" Purple tang so I am still on the fence if I should buy it. I believe spreading the aggression would be a key to success, seeing multiple same shape tangs will divert aggression? I could be wrong......?

Per attached video, it's not mission impossible
