Has anyone crossed highline brown hens with a French copper maran rooster??

[JarrodnJojo2016]

I’m wanting to make a dual purpose bird! I’ve got 10 highline brown hens and a nice French copper maran rooster! Has anyone crossed these? If so, what is the out come? How long dose it take for them to lay? Is this a good cross? How dark do their eggs get? How hardy of chicks are they? How is the hatch rate? Would love to see pics if anyone has done this! Thanks in advance!

Here's a recent post about the exact same matchup:
