Perhaps you could do so? I have several pieces of laminated glass
which are toughened. i.e. the laminate is a sheet of toughened glass,
the polymer then a sheet of non-toughened glass.

Not so - I have worked with glass for years and never seen such a hybrid.

Then you've never owned a car because most cars nowadays have inner
toughened glass, exterior plain glass for the windscreen. I suspect some
are going to toughened glass both sides to reduce pedestrian
lacerations. It's well-proven technology. It's also used extensively in
safety laminated glass for domestic use (link provided elsewhere).

One assumes from your cockwitted comment that you're another glazier
with pretensions of competence.
