Probably, Litecoin has a 2.5 mins block time but it didn't take off though. They have the option to use that if they feel Bitcoin is slow for them. I'm not encouraging people to use Litecoin because of what I said, invest at your own risk. For now it's not necessary to speed up the block times because the network would always be empty.
What's not to like about the Lightning Network it's like squeezing multiple transaction in to one.
block times is not the issue. its the trust of zero confirms that has been lost since ~2013
but it really is funny that people, instead of demanding devs fix zero confirm trust or fix onchain scaling. they try to tell people to just use another coin or use another network... (facepalm)
P.S LN is not a solution for bitcoin. scenarios have proved this. and also LN is not a feature that is only utilised for bitcoin, so its not something thats unique to make bitcoin better. othr coins will use LN and thus bitcoin has lost more unique benefits that separate it from other networks
