Kind of. Very similar layout of suspension. But ... they are bigger and heavier than the B310, which is the succesor of the 1200 (B110).

They really are the the size successor for the original P510, because the Bluebird series grew to be a big car, then Nissan needed one that was in the middle. Though technically there was the 610 and 710 series side by side for a while. The A10/HL510 was the direct successor of the 710, while the 510, 610, 810 then 910 was the bluebird line.

Hope I got that right.
