I believe this is your only option at the moment. And yes, it will result
in a single point of failure.

Separate blob stores... hmmm.. this might work but you'll end up wit two
separate tile caches too,
as far as I remember once the metastore is enabled GWC will check the
existance of the tile
in the meta-store too.
A solution that would require some modifications to GWC would be to have
the metastore become
pluggable and allow for usage of a centralized database, like a shared
Oracle/PostgreSQL.
And then some way for the two GWC to avoid stepping on each other toes so
that they
don't try to write the same tiles in parallel.
Cheers
