Plans we already have :
HTML to PDF
HTML to PDF so you can do server side PDF generation. Even better would be figuring out a way you can go from the HTML you get from a report using WebDirect and strip out whatever you don't need in order to produce HTML you can feed into this report. Even better, being able to do it on the fly.
Combine Multiple PDFs into one.
Like the built in append step, but with more control and access server side.
PDF optimisation. Any other requests?
