JIRA Admin Name Change Workaround

Hello,

I am the admin for my JIRA account and now that we are adding client, we want to change my name and other team members to be prefaced with our compay initials for clarity. I have researched the forums on here and see that changing the admin name is no easy feat, almost next to impossible.

I wanted to know if I created a temporary TEST user, and gave that profile all of my rights (admin, developer, ect) and deleted my current profile and created a new one with the correct name and gave myself all the same accesses back if that would be a feasible work around.

The catch is, I am the author of pretty much everything in our JIRA on demand, and am not sure if deleting me, would then delete all the issues comments workflows, etc that I have created. Please advise.
