Change firstname and familyname colors in moderncv classic & add a line below that & put the title below the line

Question

I'm using the classic theme of moderncv (version 1.1) but would like to tweak a bit the header (but I'm too dumb to do that).

1. How to make name/family name colors look like in the casual theme (i.e. the first name in grey and the last name in black).

2. Ideally I would also like to add a line below my name and photo and put the title BELOW the line.

I know I'm asking a lot, I browsed the questions but didn't find the way to do that.

You can do this with a redefinition of \makecvtitle; for example:
