Champion chapter specific voice lines

It would be nice if the champion skins had chapter-specific voice lines when equipped. For example, the Bulwark's "For MaCragg, For Guiliman...." voice line feels a bit out of place when using the Dark Angel champion skin. 
And with the upcoming Salamander one, it would be a nice touch. 
I understand that we can not get one for each chapter based on standard colors and heraldry when equipped with normal armor but it should be on the champion skins.
