What do you get when you cross a SLW with a GLW pls?

[Mountain Wampus]

As the Title suggested I'm curious what the chicks would look like if they are SLW x GLW. I have 3 GLW hens and a SLW rooster. I'm considering keeping the roo if it will throw nice chicks w the GLW hens. Does anyone have experience to share w this cross? I'm sure its been done, I just have no exp w them to draw from.

thanks
