Renaming 'Roles' in aspnet_Roles table

Hi
I think it is feasible and wont impact any other tables or functionality. There is no provision with in ASP.NET Website Administration tool  to change Roles , after they have been created.
Example: Role: Admin to Administrator 
Like to know if there are any hidden catches, if the Role text (Admin to Administrator) is changed manually in aspnet_Roles table?
 
Thanks,
