Yes. ZooKeeper has a “blob store”. See the Blob Store API in the ref guide.

Minor nit. You will be creating  a jar file, and configuring your collection to 
be able to find the new jar file.  Then you _upload_ both to ZooKeeper and 
reload your collection. The rest should be automatic, Solr  should look for the 
 jar file in ZooKeeper and pull it down locally to each node as necessary.

Best,
Erick
