As a practical endeavor, a new Constitutional Convention would be a real mess.
The THREAT of the states launching one, however, could be an effective tactic in reigning government back in. Like how FDR wasn’t able to pack the Court but his effort to do so bought about a rapid change of heart in Justice Owen Roberts; the switch in time that saved nine.
Recall that in 1994 Republican governors proposed a “Convention of the States” to propose ideas for fixing things like unfunded mandates. The concept scared the heck out of people ... To the point where the idea was dropped after the elections. No one wants a Const Convention: there’s no way of determining where it would go (like how the original Constitutional Convention was called in order to do a quick cleanup of the Articles of Confederation.)

Good! Let’s work with that idea and see where it leads us. Congress did that with Obama”care” and the SCOTUS bailed them out.
To paraphrase Nancy Pelosi: “You never know what is going to happen until you do it!”
A more realistic threat is to simply have certain states refuse to follow the feds unconstitutional usurpation of their citizens’ liberties. Instead of seceding to perpetuate slavery, the states will leave the union to prevent their citizens from becoming slaves. I can support that.
