This is fun! If we can imagine all of the things you said im going to pretend their isn't a ban either!
I would get bedlington greyhound x greyhound - I like the beddys, making it a 3/4 adding height and speed so that it will not only lamp for rabbits and bush but also give it an easier time on hares.
Then a deer grey x collie grey. My kind of hare dog, I'm not asking for a 3 out of 3 regular i like to walk my dogs and let them hunt themselves, if it was to catch all the hares it coursed I'd have no room in my freezer. Also good for the odd deer this dog.
Labrador for retrieving,
