I have a homegrown utility that will merge multiple RRD files, merging data from DSs with the same names using the best available RRA.  It lets you add DSs and so on - might be what you want.

This does it by using the RRDs perl module to query the exiting RRD file(s), and writes out an XML file which is then processed by rrdimport to create the new RRD file.

The problem is that it is rather rough.  I wrote it to merge our multiple RRD archives into a single file, though I've made it as generic as possible.  The other problem is that I can't remember where I put it :/

I'll post here if I can find it.
