half cross x half cross = half cross does it not ? and both parents could be hunting dogs..
In theory yes, in practice I would say no, as to my mind a half cross is a first generation cross. HC X HC is a second generation lurcher so to my way of thinking it would not be a true half cross. I may well be wrong, but that is how I see it.

a hc x hc will still be a hc .... it just wont be a first cross
