No, be a child channel don't prevent overwriting ...

If you sync EPEL repository directly to Spacewalk server channel, you 
put all rpms in spacewalk,  including those overwriting base OS packages.

But, if you sync CentOS base, updates, extras and EPEL repositories with 
command 'reposync -l bla bla bla ' ('-l' flag = enable yum plugin 
support) to local directories, you don't download Epel rpms that could 
overwrite base OS packages, because you are using priority plugin ...

Now, if you sync every local directories ( those with CentOS base, 
updates, extras and EPEL rpms downloaded above) to spacewalk channels, 
you don't upload rpms that could overwrite base OS packages, because you 
have never download them ...
