No direct workaround, no. It is a known problem, with no easy solution, as
keeping track of which rows have been replicated to which fraction of
an existing sync is a tricky (but solveable) problem.

A future version will have a sync-level option that tells Bucardo to drive
on, continuing to replicate to what it can, and then autmatically cathching
the flaky servers back up once they come alive.
