It may "work" in a very restricted sense but, as Bernd pointed out, it
will not work at all well with the rest of LaTeX.

Note that this is not part of LaTeX:

Two rules of LaTeX:

-- In LaTeX, printable ascii characters NEVER change their catcode from
that assigned originally asigned to them, even when using inputenc.

-- And all characters keep the same catcode throughout the body of a
document.
