Security is not easy. IMHO SELinux is a worthwhile investment of effort.
It is also completely different from LIDS and performs a different
function. LIDS attempts to detect that an intrusion has happened.
SELinux tries to prevent the intrusion happening in the first place, and
to limit the damage that occurs if it does.

Yes it would.
