Things I like: 4
Seargent with thunder hammer: Although probably not the best bang for your buck, I love the fact that you have a random dude in power armor toting a thunder hammer, I'm sure the model will look super awesome, and worth the extra 5-10 points over the power fist (imho).
MM Attack bikes: Good solid chasers with relentless, T5 multi wound models that halt advancing armor- essential for any BA list imo.
Predators: Kitted out the way I use mine for the space puppies, incredibly effective.
Jump pack marines: Very fluffy, even if it is just one squad, to top it off its the same squad with the thunder hammer. Cruise control for cool.
Things I dislike: 2
Lack of feel no pain- I know you have a sanguinary priest, but when you can give all your troops feel no pain for 50 points a squad, I find it difficult to not try and find a way to fit it in to every list. FNP is such a Godsend for marine lists, 3+ 4+ makes it difficult to lose marines to small arms fire. Also, its incredibly effective in close combat as most models do not have power weapons.
Razorback- I don't think the heavy bolter is going to do much for you, a STR 5 gun is cool for anti infantry, but you have alot of assault marines which are by far more effective than 3 STR5 shots. I see the direction you were heading in, but I don't think it'll be worth the points. Atleast if taken as a rhino, you can disgorge your squad and use it as a backup for an assault squad that lost their rhino.
All in all your list looks super fun, I'd play test it for a little while and see if what I said holds true. If not, more power to you. Assuming what I said does come to fruition, I'd consider getting those sang priests, which seem like the backbone of any BA army (who doesn't want FNP and furious charge in an assaulty army?).
Just my two cents.
edit:: apparently you beat me to the punch on things like the furioso dreadnought and adding a librarian. Touche.
In the trenches, unless the Commissar is stupid or insane, he would probably defer to the Marine. If 10 feet of blood-splattered power-armoured killing-machine with a pistol the size of your head and a sword taller than your chest said "Cover our flank" you'd probably cover his damn flank and not start debating the finer points of command structure with him.
