Since branding is so important this really seems like something that should go through focus groups or crowd sources somehow? Maybe a poll on hacker news? Unfortunately, I really think changing the name would be critical to the success of the project. Imagine you are a technical lead and you have to convince your boss to switch from RHEL to Rocky Linux...
Edit: I know the name is in tribute to Rocky McGaugh, but I still think "Rock Solid Linux" "named in tribute to CentOs co-founder Rocky McGaugh" would make the project more successful
