Hi Tom,
without having gone into the details yet, thanks for the great effort you have put into this research and implementation already!

Have you also considered using just an index from a sorted UTXO set instead? The potential additional space saving might be minor but this would make the scheme compatible with pruning. I had this on my list as a future research topic but didn't get around to it yet.
Thanks,
Fabian
