But you have observed that you cannot do everything with a
code substitution: a function call does not only depend on the code
but also on other properties of the function object: e.g. the
parameter processing.

You might be able to change them in a similar way as "__code__" (i.e.
direct modification). Otherwise, you would need to construct a new
"function object" -- and lose the possibility to completely
change the function object in place.
