Definitely bro, try some para comp/distortion and see if you like. Might work, might not. =D
For the vocals, try a steeper highpass (dont know what you have it set to know) and a low-pass as well.
I remember para comping/distorting the vocals as well on the pop/punk band I did. I know I used Massey's Tapehead which worked GREAT for this stuff. I used it all over the mix, actually.
The vocals just need to be thinned out a bit to get them to sit better, really. That and some slight grit will make them loud and still intelligible, but not so much that it becomes a distraction, which is kind of how they're sitting now.
Then again, don't mind me, I'm known as a guy who likes to tuck vox quite a bit compared to others who want them to just be like BAM HERE I AM.
In the end, whatever you like, go for it!
