[MW:30822] Two Base metal different thicknesses on same PQR

Hello dear colleagues, 

I hope this email finds you well

Code: ASME IX

In order to qualify a WPS, one client proposed to me to weld and qualify only one PQR test plate composed of 2 plates with 2 different thicknesses (12,5 x 9,5mm).

Does this proposal make any sense, regarding obtaining more open qualifications in terms of Base Metal thickness, I mean, 1.5 to 25mm?

My belief is that must be welded 2 test plates 9,5 x 9,5mm and 12,5 x 12,5mm. 

Is my interpretation of 2 different plates, too rigorous and narrow-minded?

Thanks in advance.
