The nearest solution I can propose, is to define a new function
bool() of one variable and use, say, bool(x) and bool(y) instead of
your Boolean variables x and y.
The point is: for a function you have possibility to define
its own behaviour under exponentiation, in particular,
bool(x)^2=bool(x).
Best wishes,
Vladimir
