Yes, Rolls Royce are making a similar sales pitch for their slightly larger (470 MWe) SMRs - they can be built on the site of decommissioned 1st gen reactors or paired to directly replace old coal-fired plants.

There's a chance that it might work out reasonably well, depending on how long they take to build and bring into service in practice. If it can be done quickly enough (RR claim 4 years) then it'd be a useful fillip while the renewable buildout is ongoing and the system is still grid-constrained.

In the medium term, it's unclear whether it can be competitive with the alternative of just turning those sites over to batteries, but it's probably worth a try as a hedge against some sort of unforeseen problem with scaling out storage.
