I could be mistaken, but in a Constitutional Convention, any or all of the current Constitution could be repealed or modified, but whatever the modification might be, the states would then have to ratify the changes as if they were a series of Constitutional Amendments.......
For example of the 2nd Amendment were repealed, it would not take effect unless the states approved...

The amendatory process under Article V consists of three steps: Proposal, Disposal, and Ratification.
Proposal:
There are two ways to propose an amendment to the Constitution.
Article V gives Congress and an Amendments Convention exactly the same power to propose amendments, no more and no less.
Disposal:

The State Ratifying Convention Method has only been used twice: once to ratify the Constitution, and once to ratify the 21st Amendment repealing Prohibition.
Ratification:
Depending upon which ratification method is chosen by Congress, either the state legislatures vote up-or-down on the proposed amendment, or the voters elect a state ratifying convention to vote up-or-down. If three fourths of the states vote to ratify, the amendment becomes part of the Constitution.
Forbidden Subjects:
Article V contains two explicitly forbidden subjects and one implicitly forbidden subject.
Explicitly forbidden:
Implicitly forbidden:

Anything can happen.
The original Articles of Confederation required unanimous consent amnong the 13 states in order to be changed. The constitutional convention that wrote the current document arbitrarily decided that 3/4 would be sufficient.
Does anyone really think they can control the outcome of a convention?
The states that ratify or reject by legislature are more apt to render an honest judgment than those states that put it to popular vote because the Peoples Democrat Party is in the process right now of taking total control of the voting mechanisms from top to bottom and enacting vote fraud into Law.
