Part of the upgrade cost for a Chapter Master goes towards his Orbital Bombardment, and by using Artificer Armour you are missing out on the opportunity to move and fire it, upon deployment. Enter the Terminator Armour upgrade, instead. Artificer + Power Fist = 45 points. Terminator Armour + Power Fist = 40 points... and relentlessly firing your orbital Bombardment. You've got space in the Pod, might as well use it.
That would only be 5 more points than your current armour / weapon load out.
In a mobile Tactical unit, I'd prefer Plasma over Grav Guns. On the move, you've got equal volume of fire at 9", and greater firepower from 9 to 24" away. If you're disembarked early, you have greater range [equal to the cannon] to attack enemy units. Having worked with Scions from the Guard, I can say there's a... thing... about 9" range that just doesn't work well. Probably just because I'm used to 12" increments, but that 9" always seemed to be just not enough.
[Tee-hee. Inches.]
As to the Siegebreaker Cohort... do you have many "buildings" in your meta? We very seldom use buildings, almost always ruins. If you aren't using "buildings", then the first benefit is null as you only get re-rolls against buildings. The second benefit has a lulz effect against passengers, but only the passengers. No benefit to wrecking the vehicle. Unless you're frequently assaulting loaded transports, that's also a pants bonus.
The reason I bring it up, is that you could roll those selections into a CAD, and then instead of an Ironclad you could take a Regular Dreanought with a longer-ranged gun. You're only losing one attack... and the Dreads all have lots of attacks now. For significantly cheaper, you could be rocking a TL Autocannon, or Assault Cannon to provide fire support / melee deterrent to your Rhinos. Just have him walk along behind, gaining cover from the tanks.
Because with 50 or so points left over, and a handful of points saved, you could buy TWO Dreads, make them a mob, and have them march along with your Rhinos. Have them do the switcheroo if one takes a couple HP, so you can maintain two functioning models.
To keep 3 Pods, you could buy one for your Devs, and drop it, empty, onto an objective. If you figure the pod is roughly 4 inches across, if you start a drop on top of an objective, you have a 52% chance to drop within 3". I've won games that way.
I always want to buy Deathwinds, and never do. They're a fun luxury, but still a luxury. Whatever you're dropping your Assault Cents onto probably isn't going to be afraid of a handful of Heavy Bolter hits, you know? Especially if you're rocking some flamer goodness on those models. The extra range on the SB's has occasionally proved useful for sniping the last model from a unit... I always want to take DWL, but always run out of points.
And yes, ALWAYS buy Dozer Blades! Cheaper than they used to be, and a cover save is more valuable than it used to be.

[1797 - Total]Well, crap, now 47 points over. My personal suggestion would be to change one tactical squad over to a Pod. That would save 40 points right there, and keep the 3 pod ideal. From there, trim 7 points as desired.
If part of the strategy is to have the twin Rhinos, I'd ask how attached you are to 3 pods, because then you could drop a Pod, and then either the Vets from the Cents, or maybe one Dev... there would be options.
Maybe drop the Vet Cents, one Dev, and drop a Grav Cannon for something else in a tactical squad?
This style list is something I'm looking to try in my next game, Dreads marching with Razorbacks.
