If i have a digital filter running in code with B0,B1,B2 and A0,A1 @ 20khz and I need to build an equivalent analog filter with the same response. How would I do this?

one simple way you may try is a bilinear transformation to map your filter to the s plane...cant a transformation then be made to approximate this in continuous?
