Maybe.  I think the main reason for the 1 Mohm resistor normally used
in wrist straps is safety: if you touch a live wire, you won't get a
substantial current via the strap.

Another issue with aluminum foil is that it's coated with an excellent
insulator (aluminum oxide) which may or may not be thick enough to
interfere with what you were trying to do.
