Although this approach is used for the hihat/cymbal generator in a lot of analogue drum machines - look at the circuit for the TR606 for example.  A single Schmitt trigger is wired up as a rough square-ish wave oscillator and mixed the others to form a complex metallic noise.  Two of them are tapped off for the classic 808 cowbell.
