Read 314.28 (A)(2) carefully. The last paragraph says;
"When transposing cable size into raceway size in 314.28(A)(1) and (A)(2), the minimum metric designator (trade size) raceway required for the number and size of the conductors in the cable shall be used."
In other words you size the box off the minimum conduit size allowed for the wire, which is 2" and still run the oversized 3" conduit. Oversizing the conduit does NOT mean you have to oversize the pull box.
So the minimum box size is 2"x8=16"
and 7 1/2". Something like 16x12 or 16x16 is probably more reasonable.
