IIRC the extra troop slots for Word Bearers can only be taken up by demon packs. I'd suggest double checking that, and I'll do the same tonight.
Let's assume you can take 9 CSM as troops. In that case, I'd suggest dropping the havoks and the chosen squad, which nearly nets you enough points to get 2x 6 mounted demonettes. Not only are they awesome, but such a static list would be best served by a demonic cc unit that can really slam out from the gunline and tackle things up close and personal. Second, I'd suggest trashing the retinue and reinvesting in some real kit for the HQ - accursed crozius, combi-bolter, etc. Make him a nasty counter-assault force that can really support his troops, by making them fearless and backing them up in combat.
Does this take CSM away from your horde of them? Yes. Does it give you at least a little taste of combat power and a smidgeon of flexibility? Yes. Does it assume you can take 9 CSM squads as troops? Yes

EDIT: Going off my changes above gives 158 points for HQ. Here's my suggestion:
Lord - MoCU, cursed crozius, combi-bolter, terminator armor, mutation, strength, visage, spiky = 158
This is assuming 25 points for the crozius, and the terminator armor is largely for modeling purposes, though it does give him 5 attaks (+ reroll) base ...
