triggering an acustic drums but not the cymbals

[Onizuka]

How do you manage to maintain the full sound of cymbals when recording an acustic set without any bleeding or peaks by snare,bass,toms?
Idea is to regulary record a regular drum set and replace it with some power samples,but leave that beaufull cymbal sound and stereo image.

I use dynamic mics(akg401,sm58,d12) on the drum so later I can just use drumagog or KTdrumtrigger to replace real track with samples,but sound in the overheads(akg c1000s) is full of unwanted peak from the drum(besides the cymbals).

I tried with massive dumpening of the drum-heads,but it's just not quite enough,and the snare (heavy dump) is the killer!Overheads picked him up almost as loud as the snare mic.
the drummer,is way close than perfect,so i thought I can count on sample replacemant to fix the drumming,but the bleeding is to much of a problem.

How do you solve this problem?

It's kinda an emergancy,so help me fast.thanks-a-lot!
