Does EASA not have a Contact Approach procedure? It is in 5.4.25 of the AIM but I don't know how to include a link. Candidly, at least one of our controllers here did not know about this...
No such thing. But in practice it's pretty much what the OP asked to do - clearance for a IAP through the cloud followed by a visual break once in the clear, with obstruction clearance left to himself.
