I think you're going about this the wrong way.
First off, you need to stop mixing with your eyes and rely more on your ears. Don't worry so much about what the mix LOOKS like, just what it sounds like.
It's an exercise in futility to try to eliminate the peaks in a dry rock-drum loop, because drums (especially punchy rock drums like the ones in your loop) are predominantly transient. If you were to somehow kill the transients you'd be maiming the drum sound - the drums are SUPPOSED to poke through the mix a bit in a drum-heavy rock/metal mix.
Once the rest of the elements of the mix are added, the peaks won't seem so drastic - in one loop you added bass, but the drums are so much louder than the bass in that loop that their transients are still going to dominate the resulting waveform. If the drums are the loudest thing in the mix, they're going to stick out in the mix's waveform - beyond several stages of compression, a very fast limiter with a high ratio or a clipper (all of which will affect the original drum sound to some degree) there's not much that can be done to change that.
As far as saturation goes, even though it's adding a degree of compression, it's most likely very gentle compression (low ratio/gain reduction) so it's probably not going to do much to reduce the peaks in the drums unless you hit it REALLY hard (which will most likely noticeably distort your drum loop).
Just some food for thought...
