Litecoin for Liquidity?

I've finally put my mind to a bit of LTC. I've made the journey from BTC and then recently to Ether so plenty of reading to say the least.

So, I'm considering LTC very closely and one reason (apart from hodling) is to have some liquidity in crypto over the coming months in the event BTC becomes unusable (ie ridiculous confirmation times) and say I'd like to purchase some ether..

Is this logic too simple?
