Our memorable nine

I'm writing a story, in the story, 9 heroes died and people remembered them as "Our Memorable Nine" and thus the name of the story is OM9. Actually OM9 stands for something else too, so the idea of "OM9" comes before "Our Memorable Nine", and I don't want to change it to "The Memorable Nine" or something else. So, does "Our Memorable Nine" sound right and is it grammatically correct?

Thank you in advance
