as far as I know, GHC simply issues an implicit import Prelude without package qualifiers. So you can get what you want by not depending on base, but rather have prelude-prime re-export all modules from base plus its own Preldue. A more modular variant would be to have a package "preludeless-base" which re-exports all modules from base but the prelude. Then you can select which prelude you want simply by depending on preludeless-base (instead of base) plus a package (say prelude-prime) which exports a module named Prelude. If prelude-prime itself wants to use base, it can still use package-qualified imports. Or it could itself be based on preludeless-base.
