No, in the 68000 family the A- and D- registers are 32 bits.
If you compare the earlier members with the 68020 and later, it becomes
clear that the architecture was designed as full 32-bit from the
beginning, and then implemented in a cut-down form for the initial 16-bit
products. Going full 32-bit was just a matter of filling in the gaps.
