That's not quite what happened.

A year after the success of the national rollout of Heart, Global execs decided to do the same with the Hit Music network. There was a lengthy discussion about the name, whether it should be Galaxy, Capital or something completely new. There was also extensive market research and the Capital name came out top in that and there were also a lot of there reasons.

The simple truth is that today your average listener (and that's all that matters) does not remember Galaxy, Leicester Sound, RAM or any of the other legacy stations with sorrow and nostalgia for the "good old times", if they're remembered at all. 12 years after the re-brand to Capital the amount of listeners inside the age group that matters, who has any idea about the legacy stations is small and becoming smaller by the day.

Obviously if the Galaxy brand was ever revived, it would target an older audience who were listening to Galaxy during it's prime in the 2000s, who are now in their 30s & 40s. It could launch as a rival to Kisstory, but as has been noted, launching Galaxy as a standalone brand wouldn't fit in with Global's strategy of their radio business revolving around their already established core brands. 
But a proper digital rival to Kisstory is about the only station that Global does not have. I wouldn't count Heart Dance as a rival to Kisstory, and Capital Dance focusses almost exclusively on newer dance music with just the odd 'throwback'.
