BTC miners have already blocked segwit , it has no chance at all of being activated on BTC,
if LTC miners accept segwit , they can kiss the profits from transaction fees Good bye.
LN will steal all of the transactions fees, and bankrupt the LTC miners.

Ask your self this, on LN offchain network BTC & LTC would run exactly at the same speed, why the hell would I bother with LN's LTC, when I can use LN's BTC.
Segwit for litecoin is a death blow to litecoin.  Moving to LN removes any speed advantages you had over BTC onchain performance.
Charlie has accepted a payoff to kill litecoin, by including segwit.
