Running my node like this will work on lightning network?
Lightning network is not going to be added any time soon to Bitcoin Core, as far as I know. Guys that came up with it are developing a client for lightning network called lnd, that will have to be run along side the Bitcoin client. They also made a full node client with segwit support and light client as a back-end for lnd. I am not sure if you will be able to use Core as a back-end, but I hope so. Either way, their full node client doesn't have wallet functionality, so wallet is not necessary for that.
Also there is no PoS in the Lightning network, that wouldn't be safe and could lead to centralization. LN just uses special Bitcoin transactions that it doesn't publish on the blockchain in a safe way that a double spend is not easy and can lead to loss of funds, as opening of a channel requires a form of security deposit.
