Unfortunately as you said dedup doesn't work with read-only snapshots (I 
only use read-only snapshots with snapper) :(

Does dedup's dedup-syscall branch 
(https://github.com/g2p/bedup/tree/wip/dedup-syscall) which uses the new 
batch deduplication ioctl merged in Linux 3.12 fix this? Unfortunately 
latest commit is from september :(
