It sounds like the deferred job plugin will work as a mechanism to manage
the jobs, once there is a tool that communicate to two different galaxy
instances via the API and order them to start transferring/loading files. I
think the tools '__EXPORT_HISTORY__' and '__IMPORT_HISTORY__' (under
lib/galaxy/tools/imp_exp/), but with some options to select subsets of
elements from a history, would be useful in the case. Then I just need to
command them via the API.

But there still may be a problem with mapping IDs between the systems...
