Greetings!
Here is a way to switch up your current list, trying to use the models that you have.
Split the noise marines into 2 squads of 5, each with a blastmaster. Keep these guys far back, getting maximum use out of your 48" range. The
str 8
ap 3 small blast is awesome, but it counts as a heavy, so moving and shooting with it is a no-no. This means I would drop the sonic blasters. Plus, the noise marines are fearless, so getting
VOTLW on them is pretty redundant

. This frees you 51 points.
For my personal taste, I would drop the
lvl 2 sorcerer, for a
MoS lord, saving you 20 extra points. This also allows you to get your 2 squads of noise marines as your troops choices. Then, your could use your 2 squads of
CSM as 1 more squad of havocs, and one squad of chosen, and I would equip them each squad with one lascannon. This gives your list some nice
str 9, and the 48" range goes well with the range of the blastmasters, forge-fiend, and the autocannons.
Doing all of this would leave you with 46 points, plus the 4 that you already have left over, giving you enough points to grab a squad of cultists. 10 guys are like 20bucks or so in case you dont have them. Put both of your
hq choices with the cultists to give your sorc a whole bunch of bodies to eat shots while he throws out his powers. If you roll frenzy, you can use it to buff up your cultists and lord, and if you roll symphony, you can still buff your bm's.
Something to think about
