Will it be easy to add support for preprocessors?

Classic Hugs has a flag -F for specifying a preprocessor for all source
files, and I've hacked an option to redefine the set of source file
suffixes.  Then the preprocessor can be written to do different things
depending on the suffix.  Is this sort of thing compatible with GHCi?
