By far the quickest and best way to solve your dodgy walls is addressing the issue at source, so tell the joiner the walls are unacceptable.... I know, he thinks your a magician that can fix everything by 'building out'... Yes, but you ate limited by bed depths with most adhesives + would probably involve dot dabbing type install rather than the easy way it should be. Only other option is dry lining or rendering both of which are unnecessary given the fact you have chance to fix now.
