To update this thread, I ultimately was able to avoid a bscan of all my backed up media by restoring a backup of my catalog database. I have set file, job, and volume retention to 1000 years.
Does a virtual full job strategy eliminate information about changed files? ie, if the full backup captured fileA in one state, and if a later incremental backup captured fileA in a different state, would the virtual full consolidation process eliminate reference to the first backup of fileA? Lets assume that once a tape is full it, nor its associated files or jobs will never be recycled, at least not for a 7 year period or so. Incrementals forever could scale very badly in a larger enterprise, but my objective is to protect a single set of files on a single system. My largest concern is tapes going missing in an incremental chain, and for that reason I'm probably going to need to do differential backups periodically.
