I tried to use https://github.com/CryptoManiac/stratum-mining-proxy but it failed, with the following error:
INFO proxy jobs.extranonce2_padding # Extranonce size mismatch. Please report this error to pool operator!
Remember that Novacoin is not only scrypt, but a PPC protocol coin, so it would have to be modified further to mine a Litecoin scrypt type coin.
If you are trying to set up a private pool, you really do not need stratum.
I wrote up a quick guide to using FC with pushpool here:

If you really want to setup stratum, there is a eloipool fork for scrypt coins at:
