Using a Rolland or its future larger replacement for potting pirates might be described as a definition of classic overkill. Probably the pirates will be using ships just large and powerful enough to prey on unarmed merchantmen. Thus the need for a smaller, cheaper new pirate suppression warship.
Enter the Frigate. Kinda like our late cold war United States Navy Knox and Perry class vessels designed pretty much just to handle enemy submarines. These new small cheap star ships would be designed just to handle pirates. Thus the need for many new cheap small Frigates. Corvettes are too small.
Just me. Kinda also like the BIG sub chasers of WW2 in the Atlantic. Cheap, slow, expedient, weak, but good enough for the job at hand. No more than that. But also strong enough to take on the occasional larger pirate ship. Post war conditions are going to very interesting. HB of CJ (old coot) Cm.
Armed merchant cruisers may suffice for that.
There will be a few years in which you'll have lots of little opposition with no multi-drive missiles. ("Multi" here meaning over 1, including a CM drive.) For that, you could get away with whatever.
But you'd be putting a whole lot of money and people into units that would be ineffective - death traps - against any modern units, even someone with a stolen missile pod. You'd have units that will be able to serve no regular military purpose immediately, and no armed purpose whatever against opposition in ten years. The reduced crew requirements of modern ships mean vastly reduced operating costs, and construction costs do not increase in direct proportion to tonnage either. So you'd be saving much, much less than you might think.
Even for just being the single platform for detecting and blowing away nearly defenseless, nearly harmless targets, the dinky ship will be at a profound disadvantage compared to the larger one, with recon drones the larger ship can support easily and the dinky one just can't. The FTL recon drone means that, as a sensor platform, the small hypercapable ship with maybe one of them is profoundly outdone by a larger one with a whole brood of drone. And giving the larger unit a longer cruising range is much easier too, so it's out there on the job a longer time at a stretch.
The dinky platform has competition from the other direction, too. Where hyper-capability isn't a strong issue - when you're content to make your defenses tied for long periods to a single system - LAC's and system defense pods will do the job. There may be many systems that won't have modern LAC's or MDM system defense pods too soon, but if you've got a choice between building them such units that will be useful as far into the future as you can predict, versus units you
know are already obsolete... it's a no-brainer.
If you want to use something to fill in between now and then, I recommend the ships of the Solarian League Navy. They're already built and no longer useful for fighting wars.
