Not that it's necessarily a good idea, but you could make the top-level package a wrapper with a custom import subroutine. That sub would examine the version argument passed and itself require Module::Version1 or Module::Version2 and then arrange for the appropriate exporting to be done from those modules back into the caller's namespace.
