ATAT Raid

I have an idea for this raid with the ATAT 1st phase. Darth Vader and 2 snowtroopers then in the2nd phase the ATAT with 2 heavy cannons and two light cannons to destroy to topple 3rd phase same weapons but this time it gains 100 defense without negative effects and for all three phases it's instant defeat ability will call an orbital strike on all enemies and massive damage to the main target. The last phase the ATAT will not have the instant defeat ability but will a have 10 more offense for every enemy without a positive effect. Rebels and droids will gain effects like the Jedi jawa have for the Aat raid. The rebels gain 20 percent offense and defense and droids do more damage to the ATAT if it has negative effects. Six stars and up like the Aat raid. Let me know what you think and if it should be implemented with the other raids
