That is exactly what the Lincoln supported Corwin Amendment said. This amendment passed the congress with mostly Northern state votes. It was ratified by five northern states.
So yeah, that's exactly what the North was going to do.
why do the articles of secession from all of the states mention slavery as a reason for seceding?
Because that is a lie. Only 4 mention slavery as a reason for secession, and even at that, they mention a whole lot of other stuff too, but people have been taught to only remember the slavery part, and not at all the other things they complained about.
And most of the states did not mention slavery as a reason. Certainly Virginia did not say they were leaving because of slavery. They said they were leaving because the Federal government had become tyrannical.
Lincoln didn't think he could abolish slavery, and this was an attempt to prevent more states from seceding over the issue while preventing the spread of slavery. Then the first shots of the CW were fired, and that was it for this amendment. At that point, he had additional powers that he could use to abolish slavery, and that's what he did.

I know, I know, it was about states rights, but from their pint of view those states rights included slavery.

You mentioned that several times in your other post. Do share, what is the state's right they seceded over?
Certainly Virginia did not say they were leaving because of slavery. They said they were leaving because the Federal government had become tyrannical.
"and the Federal Government, having perverted said powers, not only to the injury of the people of Virginia, but to the oppression of the Southern Slaveholding States." Their words, not mine.
