I don't mind it. I know a boy named
Laine Quinn (not
Layne, I know, but still).
Quinn is his last name but I always thought it would make a good combo.
I think it would work best as a MN in your family, for a girl or a boy. For boys I'd give it a simple but obviously masculine fn, since
Layne (
Lane,
Laine, etc.) is unisex and the
Layne spelling is probably more common for girls.
