LXC convert to new Zerocoin possible ?

Zcoin and ZCash are the only two cryptocurrencies that use zero-knowledge proofs to guarantee zero-knowledge financial anonymity. There are various tradeoffs between using ZCoin and ZCash. Zcoin uses the Zerocoin Protocol (cited by academics 208 times, at time of writing), whereas Zcash uses the Zerocash Protocol (cited by academics 104 times, at time of writing). The cryptographic properties of Zcoin and Zcash supplement each other quite nicely, and a good way to describe them would be sibling cryptocurrencies.
