First you'd have to define an interface to which the module writers would conform. My guess is that "modify every function in my program" does not really explain what and how to modify it. You are at the incorrect level of abstraction to make this work if you're going to have everything be function pointers.
Basically, you first want to define a concrete set of functionality that module writers should be able to hook into. Then you have to specify an interface agreement that the module writers can conform to.
One of the first things I think you may want to define is a procedure to initialize the module. Part of this could be that the module passes you back a set of function pointers (into itself) that you can call. You define the datastructure that gets passed and the module conforms and uses it to tell you want it wants to overload or hook into and passes you the callback or overload routine it wants you to call.

test::data
Data(3pm) User Contributed Perl Documentation Data(3pm)
NAME
Test::Data -- test functions for particular variable types
SYNOPSIS
use Test::Data qw(Scalar Array Hash Function);
DESCRIPTION
Test::Data provides utility functions to check properties and values of data and variables.
Functions
Plug-in modules define functions for each data type. See the appropriate module.
How it works
The Test::Data module simply imports functions from Test::Data::* modules. Each module defines a self-contained function, and puts that
function name into @EXPORT. Test::Data defines its own import function, but that does not matter to the plug-in modules.
If you want to write a plug-in module, follow the example of one that already exists. Name the module Test::Data::Foo, where you replace
Foo with the right name. Test::Data should automatically find it.
BUGS
I'm not a very good Windows Perler, so some things don't work as they should on Windows. I recently got a Windows box so I can test things,
but if you run into problems, I can use all the patches or advice you care to send.
