One thing to consider is that ply is fairly isotropic - it bends with much
the same stiffness in any direction. A laminate of thin ply and thicker
strips will be stronger in one direction than the other at right angles.

Having said that, if you search the archives, you will find somewhere a
boat built from a stitch and glue design, but made by gluing up panels
from strips and cutting these just as if they were ply panels. Those
panels would be even more anisotropic than the ones you are planning, so
that is a good indication that your idea would work.

One idea that might make the boat look good (or not) would be to mark out
the panels and laminate on the strips with a full-width strip along the
edge of the panel, with the rest filled in, much as you would strip a
hard-chined boat. You could use the same material for all the strips, or
could use a hardwood strip along the edges which would become the chines
and keel. This would give you an edge in durability terms whilst still
keeping a light boat...
