I doubt we'll ever see broadside launchers for Apollo control missiles, to be honest, especially given that there's a debate on whether an SD(P) even needs broadside launchers at all and no-one (at least not in the SEM, Grayson, RoH or Andermani Empire) is going to be building ships of the wall that can't lay pods any time soon (I'm not counting CLACs as ships of the wall here).
You can launch all the control missiles you need from your pod rails, and the hand-off ability of KH2 means that a ship which has lost the ability to launch its own control missiles can still contribute to the fleet's fire. Putting in a larger missile tube just means putting in a larger-diameter hole through your outer hull armour, to no real gain in capability.
I'm not sure that we'll see the full FTL comm setup in a missile, though. The Apollo control missile isn't just FTL comm, it also has a large tactical AI system on-board. If this was minaturised to the point that it could be fitted into a shipkiller, then the same minaturisation and increase in capability would also be applied to shipboard ECM and decoys, negating the effect.

I think the RMN found that retrofitting Gryphons to fire MK23s internally wasn't very effective and they preferred to build new SD(P)s because of all the other technical improvements that could be included in the design. Also, Gryphons aren't fitted with Keyhole 2(or even 1), which is essential to the operation of Apollo's FTL control links, so it seems very unlikely that they would be able to fire control missiles internally - not to mention Apollo is a relatively new innovation and the RMN hasn't had time to refit Gryphons with those. The MK23 firing Gryphons were converted before or during the Havenite ceasefire.
IMO, by the time they get around to fitting shipboard ACM launchers, each missile will be fitted with its own FTL communicator. This restores the 'dreadnought' principle of uniform main armament and eliminates the risk of a few early battle hits taking out the control missile launchers and crippling Apollo capability.
