With sure not. In Europe acc. to e.g. old EN 288.3 & new EN ISO 15614 if WPAR i.e. approwed WPQR refer to double or even triple sequence of test piece(s), -allowable is to use the first one methode separatelly like single methode or double methodes but in this same original order. From 141GTAW/111MMAW for tubes is allowable to use single 111 for double side plates welding with root pass gouging/outgrinding. The standards states many limitations but as the rules all are very logical.
