Probably, which answers the concern there, but you still have 
package splits differing. Fedora has tarball-level splits. Other 
distros do app-level splits (Debian(-based) at least, though not 
RPM could still happen with an RPM distro). Still a filelists 
issue. You also have package naming to deal with.

Though I suppose is a moot point as well if it's a side-effect 
of sharing spec files.
