I would urge caution about this parent sheet thing.  Make sure the so
called parent sheet is indeed the same paper.  This may require a
special job for someone to pull these out before cutting.

In any event, the Cover-90 is NOT the same as the lighter weight Pearl
White.  If there is any, and I do mean any, difference in the papers or
their manufacture, it is a good bet that they will behave differently
with an alt photo process.  You must test samples form each batch to be
sure.

It may be confusing that Crane (or any manufacturer) will label an
assortment of papers as a certain family.  This is because they are
matched for a particular purpose, like envelopes matching the
stationary, or cover sheets matching the report.  These various papers
of a certain family can certainly have very different chemical
qualities, sizing, or components which can react very differently with
processes or uses for which they are not intended, uses such as alt
photo processes.
