If you delete the locally synced data after pushing into spacewalk, then do 
a reposync, you will effectively be downloading all the packages again. 
Which doesn't sound like you will gain anything.  I guess if you just did 
the reposync on the base packages, then you could safely delete them after 
pushing into spacewalk, but with 'updates' or any other repos that are not 
static, you would have the same issue.
Here's a thought, maybe you could zero out the packages after pushing into 
spacewalk.  Which would require a custom script.  And you will need to do a 
filelist before and after you synchronize so that you could take the diff 
and only push the new files into spacewalk, then zero them out after the 
push.  That would save you from keeping duplicates of all the packages and a 
lot of disk space.  However reposync doesn't have that functionality, so a 
custom script would need to be written.
