I think a better solution might be to keep the encrypted fs on a single normal LV. Take a snapshot and send to remote. Keep the snapshot around. On next upload, take a 2nd snapshot, and send the diff between the two snapshots. The diff can be efficiently computed from the COW tables - accessible as dw-nn devices. After sending the diff, delete the 1st snapshot and go back to "keep snapshot around".
