Some interesting ideas, to say the least.  I don't if if many of them
have been done, but I know at least one has.  About a month ago I came
across a Ranma/X-Files cross over, though n my opinion it wasn't very
well written and seemed to make fun of both shows.  I feel many of these
ideas (including Ranma/X-Files) could turn out to be good stories if
taken seriously by the writer and not done just as an afterthought.
   Well, that's all I have to say about that.  Ja ne.

Sincerely,
Andrew Hubbard
