I doubt that you can redefine brackets in LaTeX. I don't think it is a PGF math limitation, but a LaTeX limitation. Brackets are used to delimit command options in LaTeX. In PGF math expressions, brackets are used to access a particular element of an array, but this is just the usual LaTeX command option notation. Perhaps you could change the definition using catcodes, but that seems like a dangerous thing to do.

You are more likely to have success modifying MathObject behavior than changing bracket behavior in TikZ and PGF.
