I think you have a larger problem though.

A theory is (as Heisenberg explained in his book "Physics and Philosophy") an interpretation of data based upon unscientific, non-falsifiable, a priori assumptions on the part of the theorist. You can't really disprove something as nebulous as "hidden variables." That's not a falsifiable statement. What you can do is disprove some theory based on hidden variables. Such evidence does not apply to the possibility of other theories of hidden variables that are yet unformulated.

My understanding is that any sort of local hidden variables have been ruled out (at least, if you want to preserve causality).

I'm not a physicist, but I'd be interested in people's opinions on:

"Chaotic Ball" model,local realism and the Bell test loopholes.
