I'd like to do this sort of thing with types other than Either. Is there a generic safe coerce function?

Lemmih,
And you can "fix" it with some unsafeCoerce# magic. (:
Actually, as I pointed out, the required coercion in perfectly safe, though not implicit:
coerceRight :: Either a b -> Either c b coerceRight (Right b) = Right b
