It sounds like a good idea to me.

There might be some details to trash out, e.g. the granularity of
packages - should there be a Quickcheck-orphans with Arbitrary
instances for many structures, or separate packages
(quickcheck-containers-instances, quickcheck-array-instances, ...) and
perhaps a new top-level Hackage category is needed so people know
where to find them - "Canonical instances", "Orphan instances", ...?
