Generally, it's possible to merge the the file sets from 2 repositories,
such that the revisions will be chronologically correct, and all files
are available in the final repos. However, I don't think it's possible
(at least easily) to merge to repositories while preserving old revision
numbers. So if you do this chronologically-and-historically-correct
merge, all the references to "fixed in rev xxxx" will be "broken".
I've spent a long time merging a number of repositories, and I'd be
happy to help if you need some tips on how to proceed.
