One possibility would be:

* Create a new repository.
* Pull from each small repository. After having done this for all small 
repositories, all branches from all repositories will coexist in the new 
repository.
* Rename the files in each of the branches such that they will be at the 
right place in the end. E.g. for each file in 
./dokuwiki/plugins/servlog/, run "hg mv <filename> 
./dokuwiki/plugins/servlog/<filename>".
* Merge the branches that you want to develop together in the future.

If you want all the history to be interleaved instead of just merged 
together at one place, a more sophisticated solution is needed.
