per 3 eighth, or 1.67 ss per eighth.

Yes.

Why would one force them to be the same length? If we have an
equalizing infinite force applying, it would force the b stem to be
1.67ss shorter than the c stem. Of course, the usual beam scoring would
apply in order to make sure that no stem gets too short.
I don't get your point.
