that wouldn't work as there's no such thing as sign off for planning. If you swap it for an opening window that is just further development that doesn't have permission. It would be a waste of the old window if you bought it only to throw away.I’d get it signed off with whatever they want and swap it for a proper window the next day.
Building regs do get signed off, but that's just a certificate, things can stop complying when changes are made, although if the aim is to sell the house the certificate would help that.
