Second, even if the premises of that post is true and 2.5-minute confirmations are more secure than 10-minute ones, it would be much easier to change Bitcoin to 2.5-minute blocks (which is a relatively trivial change as long as the majority of miners agree) than to switch to Litecoin losing tens (probably hundreds) of million dollars invested into the Bitcoin network security.

Enormously flawed reasoning in that paper. Confirmations are confirmations. Read Satoshi's whitepaper. There is no time component to confirmation security. The paper incorrectly compares 6 bitcoin confirmations to 24 litecoin confirmations. An entirely invalid comparison.
