Disagree. That would hurt all of them.
In Scotland, for example, Independence is as big an issue as Brexit. While there's basically a single nationalist party, there are three major unionist parties (potentially plus the Brexit Party although I don't think they'll get many votes). If Labour and the Lib Dems seem too pally with the SNP then it will cost them votes to the Tories. I actually don't think there's any reason for a "remain alliance" in Scotland as the SNP are polling strongly and the Lib Dems have taken a lot of votes off the Tories. It is possibly Scotland will be entirely yellow of various shades after this election.
In England, there is a pretty widespread assumption that a substantial majority of people who vote Labour prefer the Lib Dems to the Tories, and vice versa. I am not at all sure that is true, and particularly in marginal seats. If you're voting for the third party in a two-way marginal then chances are you don't think much of either of the main options and might not vote at all if they were your only options. There are lots of people who would never consider voting Lib Dems because they perceive them to be too European, too soft on crime, too pro-immigration. Perhaps more significantly, there are a lot of people who would never vote Labour because they think they're too supportive of Scottish independence, too keen on tax rises, too antisemitic, too "led by Jeremy Corbyn".
In 2015 the Tories got a majority because Lib Dem voters switched their votes to the Tories to stop Miliband. If, for a second, the Lib Dems looked like they would work with Corbyn, there is a good chance that would happen again. The Lib Dems would fall back to 8% and the Tories would be up around 50%.
If you want to beat the Conservatives then don't look for ways to rig the game, because they probably won't work. Look for ways to
win the game.
