Firstly, the Sag-C is the minimum width required for both broadsides to have DDM launchers. This means a DDM CL needs to be as fat as the Sag-C - and it loses compensator efficiency if its length doesn't match.
Secondly, the Roland packed all its DDM launchers into a very unconventional hammerhead arrangement whereby its launchers are fed by the same magazines and loading mechanisms. This system is indeed very compact, but it's vulnerable to battle damage. One hit potentially kills half this ship's missile firepower.
The other issue is that the number of hammerhead DDM launchers appears to be limited by the inner diameter of the forward impeller rooms - because they stick back into the main hull through the ring they form. And my understanding is that a Roland's 6-pack basically fills the usable diameter.
So even if BuShips were willing to accept the same vulnerable arrangement on a larger CL I don't think the impeller room interior diameter would increase sufficiently to squeeze any more tubes in. So you'd have a CL with exactly the same throw weight as the earlier DD.
OTOH you should have room for slightly bigger magazines, and could enlarge the crew, restoring some marines, plus some more bunkerage and stores. That increased combat and patrol endurance would arguably make an enlarged Roland a cruiser by type, despite having no more offensive power than the original Roland...
