Topic: Changing RGB colors to spot colors programmatically?

I'm currently generating PDFs with FOP. FOP doesn't support specifying spot colors; whether this is due to an XSL-FO limitation or not I cannot say.
I'd like to therefore specify a certain RGB color value in my XSL-FO file, and then post-process the PDF to replace the RGB color value with a spot color value.
I tried diff'ing two different PDFs to see what changed, nearly the entire file had been modified. Wacky.
I could try to grok the PDF spec, but would like to avoid that time expenditure if possible.
I parsed through the PDF by hand, looking for the values, but if they're specified in plain text, they're sufficiently non-intuitive as to have baffled me.
Can anyone clue me in as to how I might do this in a way agnostic of any particular programming language? Is modifying the PDF by hand a bad way to go? Can this operation be done with the Java iText library?
