I guess I'll name this kind of design "Oblongface". I predict that if these would debut after Series 7, 84 and 88 will have Forty's face style (and most notably his teeth) similarly to the rest of the super rectangles that debuted in series 7, and 96, 98 and 99 will have Ninety's face style but with the eyes spaced the same distance as the 40-faces, as the ones originally made by Cyril looked too cursed if their faces looked exactly like 90's. These designs will appear in the released version of DG6SP 2.0.
