lose the incepters. 246 points to play with, enough to buy

+1 ancient with flag (They have one in a terminator armor suit that would work really nicely, on a 40mm base). (gives a dying model near him a 4+ chance ot shoot immediately one shot or attack. Your models with lascannons can bring down enemy tanks or medium armor that way. Your models with heavy dakka batteries like the hurricane bolter can rip holes in formations of light enemy infantry.
+1 more primaris apothecary. So you can potentially heal or bring back models in 2 separate units.

That's probably about 160 points, I guess, leaving some 87 to play with.

Now your army has currently
14 aggressors in 3 squads
2 PA
1 ancient
10 centurions in 2 squads.
To each squad of centurions, add in one grav gun wielding centruion model (or change one of the 5 models to be a grav gun wielder). Thus you have
2 lascannon + hurricane bolter
2 lascannon + hurricane bolter
grav amp cannon (2 of them I think) + hurricane bolter
2 heavy bolters + hurricane bolter
2 heavy bolters + hurricane bolter.

Captain gravis 108
IFFeros 110
6 man aggressor squad with all dakka aggressors
6 man aggressor squad with all dakka aggressors 444
(That's 2 less but the squads are bigger, hopefully that lets them more likely to survive incoming fire and be able to patch a guy back to life or repair someone, or slink back out of LOS the next round to rebuild.)
2 primaris apothecary 2x60
1 ancient in terminator armor 1x? I dunno, he is probably like, 80, I am too lazy to look. If he can't take the relic for the larger bubble, then the primaris one instead.
That's a trim and lean 862ish points, but there are armies I know of who would NOT like to face them already.
Now add in.
3 hurricane/heavy bolter centurions 210
3 hurricane/heavy bolter centurions 210
4 lascannon/rocket launcher (subtle change there) centurions 440
You are up to 1722, by my math, so if you really WANT the incepters back in, you could get them, but oyu could also, for example, decide that 18 aggs are better than 12.
You could also, however, get 2 more of the most excellent lascannon/centurion missle launcher combo units to have
squad a .. six centurions
3 x (2 lascannon, 1 centurion missle launcher) dev centurion
3 x (2 heavy bolter, 1 hurricane bolter) dev centurion

squad b .. six centurions as well. Again, I am trying to make each squad big enough that an enemy army is unlikely to finish it off with one shooty phase when you factor in cover, 5++ shields, and fnp protection, and of course, the occasional use of transhuman physiology in a pinch. And if it survives being shot at, then a repair effort can bring something useful back.
3 x (2 lascannon, 1 missle) dev
3 x (2 heavy bolter, hurricane bolter) dev

If you keep the most nastiest of your guys near the company ancient and use the larger aura cheese on the ancient, and have your iron ferros running around to give people a 5++ aura, your infantry will be the suck for your opponent.
12 aggressors put out around 216 dakka a round, I believe, and 6 lascannon/missle centurions are enough firepower to delete a lot of tanks pretty fast. Chapter master proximity granting full rerolls, ignoring cover, both help them to be a greater threat than mere numbers indicated, as the enemy trying to take them down eats lascannon after lascannon from the ancient only to find the other unit still has 6 lascan + 3d3 missle shots to fire, and if he stops to try to kill them, its likely the primaris can bring 2 lascannon troops back from the dead (one per unit) to keep the good fight fighting. While you don't drop a pure horde as fast with this army, you drop more of an enmey armed entirely with tanks, which was your weak point, I think.

You are only a couple points shy of affording a lieutenant, which gives you reroll 1's on wounds, too. Perhaps I am wrong about the exact price of an ancient, or you could substitute a less expensive ancient for that one.
