This is not a new technique. The Linux fuse library has been able to mount S3 
buckets for a long time right now. Rclone can also do the same stuff you are 
proposing (GDrive, Dropbox) for free. 
They all should work with Bacula, but I don't think they are an optimal 
solution for an array of reasons. 
I deployed a few environments with the Bacula S3 Cloud Driver 
(https://www.bacula.lat/enterprise-bacula-s3-swift-ceph-and-cloud-storage-driver-quick-guide/?lang=en)
 and Wasabi, which does not charge per egress data and charges only 5.99 USD 
per TB/m. The driver is available with the [ http://www.bacula.org/ | 
www.bacula.org ] installation packages. 
For some reason, however, I could only achieve about 2 MB/s maximum upload 
transfer rate per part. Then I had to use a greater number of 
MaximumConcurrentUploads (and Downloads) - e.g. 20. 
Eventually I was able to reach speeds close to 40 MB/s, that were suitable for 
the workload. 

Rgds.
