Bird dog crosses

I’ve got a 1/2 cat 1/2 walker gyp I been wanting to cross to a gsp. I’ve hunted with straight gsp’s before and they were very gritty but hunted hard...one in particular would actually point a hog he couldn’t catch alone, which was aggravating because it was hard for the help dogs to find him. My female I wanna cross is good enough in fresh sign but lazy in no sign. I’m hoping the bird dog will add some drive to the pups.
Yea I’d like to hear people’s input on how bird crosses turn out also. Ideally I’d like them to be loose bay, but sounds like a gamble.
