Not a single name, but I believe
liftA2 mplus
is the same function, and much shorter (and more general). It uses the
Applicative instance for (a ->). Of course, it also works with liftM2.

This is probably a failure of my search fu or some other mental lacuna, but is there already a definition of this function somewhere:
\a b -> runKleisli $ (Kleisli a) <+> Kleisli b ?
Hoogling for its type
MonadPlus m => (a -> m b) -> (a -> m b) -> a -> m b
doesn’t net me anything useful.
