Super glue is accelerated by moisture, and PVA is largely water. To hold a large/long joint whilst it dries, it is quite possible to apply some 'tack weld' spots of superglue gel in the glue line, and then offer up the two pieces. The s'glue will grab after a few seconds, and hold all steady until the PVA sets. It's how I glue the thin wood stiffeners I put on the inside of my card roofs, especially. Good Luck!
