You would need to change shared.c::cgit_add_repo() to check whether the
repository already exists, but I worry that it could be a bit expensive
with a large number of repositories.

Have you considered just using scan-path and storing the configuration
in the individual repositories?  CGit will read extra configuration for
each repository from a "cgitrc" file in the repository or from the Git
config file (if "enable-git-config" is set).
