Not as written, because when you link to a DLL its name is encoded into
the import section of the resulting binary.  It's possible to do this
but you'd have to rewrite your code such that you dynamically access the
library at runtime with LoadLibrary() and only call routines in it
through function pointers obtained by GetProcAddress().
