Look at the blob related options, if you have not done so already:
http://pypi.python.org/pypi/RelStorage#relstorage-options
I do not look at relstorage and blobstorage often enough to remember how 
everything fits together. :-)

I am not aware of a method to migrate filesystem-based blobstorage to a 
relational database.

The current filesystem-based blobs should just work, as long as you have 
enabled the shared-blob-dir option and your blob-dir is shared among all 
clients via NFS or something similar.

Cheers,
