Litecoin to be exchanged with BTC directly on the blockchain with lightning network?

I read that Litecoin will be able to be exchanged directly for BTC without an intermediary exchange with other currencies on the Lightning network and SegWit. Trading LTC for BTC by sending a transaction to the blockchain would mean it would be easier to convert wealth to LTC for quick spending transactions.

If this is true, then LTC is severely undervalued at this time and will dramatically go up in the next few months. The title is in the form of a question because I wanted to see if anyone knows more about this and can confirm. Have been buying ltc.

Thanks
