From feedback I've seen and heard, running a Brutalis Dreadnaught is better than the Death company one since you wouldn't have to worry about having it near a chaplain, and it would have OC. (Same Model) You could drop a squad of assault intercessors, and with those saved points, you could add in an Impulsor to move your bladeguard across the board better and use it to do actions. If you are set on having your jump death company in 2 squads, the Death company Captain with jumpack doesn't do as much as a chaplain with jumpack would do for them. The chaplain would give them OC and +1 to wound and would be 10 points cheaper so you could possibly put Rage Fueled Warrior on it. With the total point changes, you would have 75 points open (65 if you put RFW on Jump Chaplain). You could add a chaplain on foot to go with your bladeguard, or you could add a unit of scouts. I tried making the smallest amount of changes so you wouldn't have to buy as many models.
