Librexcoin has been made several innovative things in crypto world I am sure that the dev is working hard and also doing this things for building a longterm base for the Librexcoin. About the supernetwork i am not sure if is a good idea Librexcoin join on it, for me established coin will not care supernet.

In my opinion a major problem to join supernet is that you need to hand over 10% of all coins. I think it's a bad plan to throw your destiny into the hands of others. LXC should stand on its own way.
