One solution to avoid multiple identical files are hardlinked files.
This is possible with cron-scripts running on the server to compact a 
TYPO3 installation.

for the migration it might be nice to have a choice between identical 
files changed into one reference or each file into its own reference.

Those who do the migration should know which behaviour fits best to 
their installation.
