Do you have an example of this being done in any other language? 
Essentially whatever code is being replaced, you're going to need 
to recompile it. If you're not using dynamic/shared libraries 
Adam is pointing you in the right direction.

If it is a desktop application then it is probably easiest if it 
communicates to a local service that provides the "replaceable" 
functions, when you stand up the new service the app can transfer 
the communication to it.

I can't speak to your security concerns.
