The better solution is to use a two-to-one flat adapter piece to make sure each person is centered behind the next.

Don’t have that type of two-to-one in LEGO bricks. You’d need a 1x2 plate and then plug the head stud into the middle indexing pin of said plate.
Why? The method described above already does the needed task perfectly, and without needing to design and produce a new part. Did you learn nothing from The Human Centipede (2009)?
