Who said anything about them using cobalt?
There are quite a few things already known today that you can do with nukes to change how they "explode".
Good point about the cobalt, although I seriously doubt if there's anything you can do to a nuke to change how it explodes. That area has been rather thoroughly studied in the last 3/4 century or so; unless there's more fantasy physics involved there are a relatively small number of fissionable isotopes that will stay stable long enough to be manufactured and carried on shipboard before they've decayed to where they have to be re-refined and remanufactured.
Granted, the processes involved in refining and manufacturing the stuff have probably advanced considerably, but there's otherwise no indication that the Honorverse has changed basic nuclear physics.
That said, though, there are probably a lot of things you can cover a nuke in that will absorb excess neutrons and result in a force multiplier. Candidates have to result in a very short half-life result after absorbing one or two neutrons, though, if they're going to be effective at adding to the jamming effect. By short I mean milliseconds or less.
An interesting possibility would be Li-7, which would become Be-8 on absorbing a neutron. Be-8 has a very short half-life (6.8 x 10**-17 s), which is why stars like the sun don't make appreciable amounts of carbon. Be-8 is sitting in the most favored synthesis paths.
