Well, I don't think I'd boost too much high end, it'd would more than likely just get strident than airy.
The kick is a little week. It's my guess it would dissapear in an aggressive mix. I feel that's your weakest link. How's the kick sound in the room? Is it punchy or flabby? If you don't have the sound there, you'll never get it back down the road. If you feel it sounds good and you've moved the mic around and have it dialed in as much as you can, maybe try a 3 or 4 dB boost and start sweeping it from around 4k up around 6k or so. Also maybe some parallel compression. I prefer using sub group outputs on my mixer to do this as if you have the tomms panned it preserves the stereo panning but if you don't have 'em, aux sends will do. I set up a drum mix that I'm happy with and then I'll have the kick, snare and tom tracks assigned as a stereo pair to a sub group as well as the main stereo outs, and send this sub mix to a compressor and step on it hard. I bring that back to to more channels and push that up under my existing drum mix to taste. you can put a lot of ass in the drums like this.
