My understanding is that had to do more with guest satisfaction ratings on Tower at DCA - it was something guests did once they were in the park, but they didn't cite it as something that was drawing them to the park in the first place. For such a large, expensive attraction, the fact that it didn't really serve the resort as a headlining, signature attraction was seen as a problem that could be improved upon with an influx of cash (and, it seems, some new IP). I don't love Mission Breakout myself, but it did the job of turning the attraction back into a big draw for the park.
This is all to say that Rock N' Roller Coaster doesn't seem to have this problem. It actively pulls people to DHS and they seem to say as much. That doesn't mean that it couldn't be rethemed - with all the change going on in DHS, it's possible they may do something to make it fit the park's "new personality" - but it's not really in the same situation as Tower at DCA.
