Have you looked at the stuff in the Joint Pack PLO K MA mod?
Don't know what you've already got, so can't really point out any you might not. Has to be a couple of hundred different bits of nastiness in there - I've been through the mod a few times and haven't yet tried all of them: I met the XM8 with a C mag and that romance has gone on for a few playthroughs now. If someone put the HK416 in there, along with the sounds used in the Smrter mod, it might just turn my head.
A preoccupation with the next world is a clear indication of an inability to cope credibly with this one.
