IG and DA vs chaos space marines

[andres]

Hello . I have arranged a battle this Thursday . We will be playing eternal war on standard board at 2500 pts . It will be me and my DA ally (1250) each vs an experienced CSM player . Last time being really lucky and taking advantage of the element of surprise (he came with a non competitive list no flyers etc since we are new players ) we beat him . This time however he will be better prepared . We know he plays CSM plague marines and thousand sons .
I have 60 troopers ( 9 plasma 3 melta 3 flamers )
3 heavy weapons teams
2 chimeras 
2 sentinels 
1 + 1 leman russ (both variants all options ) 
2 commissars 
1 psyker
1 ccs 
1 aegis
1 valkyrie
1 wyvern hydra
my ally can select 
40 plus terminators
2 land raiders
1 jet fighter 
12 bikes 
1 speeder 
30 tactical 
3 librarians

I have prepared a list along these lines
1CCS kurovs aquila and LC in a chimera with camo
1 lord commisar power fist
1 commissar
1 primaris psyker lvl 2
3 veteran teams 2 with plasma 1 with melta all camo cloacs
1 LR BT
1 Wyvern
1 executioner with plasma sponson
1 aegis
1 quad gun

it is almost 1250
My question is whether this list can provide a sufficient gun line so that the DA can afford to bring mostly terminators and land raiders to assault him
Also is a quad gun operated by a BS4 model that takes ordes (tank hunters or ignore cover ) be enough to bring chaos flyers down ?
Feel free to comment

This list is not really optimal for a gun line. All your troops have short to mid range weapons and you have more troops than you can issue orders to. This is my suggestion:

HQ: CCS

Bare because you don't have the models to set them up for optimal order givers. If you can get them I'd suggest getting some Vox casters, a regimental standard and some more heavy weapons teams.

HQ: Lord Commisar

This guy here will keep your blob in line and also man your quad gun (meaning it will be BS 5).

HQ: Primaris Psyker - ML 2

This guy will be rolling on divination so as to get prescience, and with a chance to get misfourtune and perfect timing. Put him in your blob to buff up their shooting.

Troops: PCS - 3x melta guns

These guys will hop in your Vandetta and ride it into your opponents back field to pop some tanks.

Troops: Infantry Squad x3 - Autocannon x3, Flamer x3

This is your blob, they will sit behind your defence line recieveing orders and gunning things down from afar. With support from your CCS, LC and Psyker, this squad will have a chance at twinlinked, ignores cover, tank hunter shots.

Troops: Veterans - Chimera, Plasma x2

Troops: Veterans - Chimera, Plasma x2

These squads will give you some mobile fire power. They can run for objectives and move to support the DA.

Fast Attack: Vandetta

Some extra Anti air, and a transport for your PCS

Heavy Support: Leman Rus Vanquisher - lascannon

Some long range anti tank

Heavy Support: Wyvern

Excellent at killing infantry, I'd suggest getting a second one some time because they work so well together
