Default help with monolithic filter design

I'm trying to design an all in one HPF, LPF, BPF with a cutoff/center frequency of 1kHz. I've made two block diagrams, one using two integrators the other using two differentiators, my problem is that for a cut off frequency of 1kHz, w is 2000*pi, and w^2 is ~40 million. These numbers aren't practical for construction of an actual circuit. I've tried moving blocks around and I haven't been able to find any manipulation that gives something practical. Does anyone have any tips? I know it would be easier to build each filter independent of the others but that isn't what I am trying to do. here's a block diagram of the filter using two differentiators:
